PlanetGeo: The Geology Podcast

In this episode, we sit down with Dr. Mike Ackerson (Smithsonian) for the kick-off of a deep-dive series on granites and granitoids. This one goes into the weeds: the 250-year history of how arguing about granite shaped nearly every major idea in the geosciences. We trace the great controversies from the 1700s to today: 🌊 Neptunism vs. Plutonism — Did granite precipitate out of a global ocean, or crystallize from molten rock? How James Hutton's fingers of granite at Glen Tilt helped kill the Neptunist worldview. ⏳ Uniformitarianism & deep time — How Charles Lyell's expansion of geologic time gave his friend Charles Darwin the temporal runway for natural selection. (Yes, the founder of biology was basically a geologist.) 🧪 Magmatists vs. Transformists ("granitizers") — The 20th-century brawl over whether granites are intruded magmas or rocks transformed in place by fluids — and how Bowen, Tuttle, and experimental petrology tipped the scales. 🪨 The Room Problem — Walk across the Sierra Nevada and you cross miles of granite. How do you make space in the crust for that much rock? The 150-year-old puzzle that's still not fully resolved. Plus: the legendary Norman Bowen "horse equilibria" letter, why H.H. Reid said "he who has seen the most rocks wins," and where the most exciting frontiers in granite petrology lie today — low-temperature magma storage, fluids in the crust, and links to geothermal energy and critical mineral ore deposits. This is Part 1 of a series — future episodes will tackle the timescales of granite emplacement, geochronology, and a return to the Room Problem. Want the intro-level foundation first?

In this episode, we sat down with Keith Rapp, senior hydrogeologist, longtime volunteer with ASBOG (the Association of State Boards of Geology), and immediate past president of the organization. We dug into the professional geologist licensure process — what the FG (Fundamentals of Geology) and PG (Practice of Geology) exams actually test, how questions get written and vetted by panels of subject matter experts, why some states require licensure and others don't, and why Keith argues that licensure is fundamentally about protecting public health and safety. Keith walked us through his path from growing up in Duluth with a geomicrobiologist uncle, to a master's in hydrogeology at Baylor, to a career cleaning up contaminated sites using microbes — what he calls hydrogeomicrobiochemistry. We talked about his current work on PFAS bioremediation, the idea of "pushing evolution" by engineering biofilm environments where microbes can adapt to degrade forever chemicals, and the role of zeolites as remediation media. We also got into the practical stuff students and early-career geologists actually want to know: how to study for the FG exam, why test scores point you toward weak domains, what reciprocity between states looks like, the difference between an ASBOG license and an AIPG Certified Professional Geologist (CPG) designation, and why writing skills still matter in a hiring pile. We closed with a conversation about AI in geoscience — where it helps, where it gets you in trouble when your name is on a signed report, and how the profession should think about it going forward. If you're a student preparing for the FG, a working geologist thinking about getting licensed in another state, or just curious about how a professional credentialing system gets built and maintained, this one is for you. The ASBOG annual meeting is in Hershey, PA this October — open to anyone interested in the profession. Download the CampGeo app now at this link.

Jesse and Dr. Joshua Davis introduce a new series on professional geology licensure, prompted by listener questions, exam study use of their podcast, and continuing-education approvals. Jesse shares starting the U.S. process by taking the FG (Fundamentals of Geology) exam and explains the typical U.S. pathway in 31 states: FG exam, geologist-in-training status, years of work experience under a licensed geologist (with some state-dependent education carve-outs), then the PG exam and references. Josh contrasts Canada and the UK, noting the UK’s Chartered Geologist is less central, while Canadian systems are province-based and may restrict the “geologist” title; Quebec lacks an academic carve-out and requires supervised experience plus an exam. They discuss rationales for licensure—public protection, minimum geology competency amid changing degree names, professional trust, insurance coverage, employability, and continuing education.

Today Jesse talks with Christie Capper, founder and CEO of Deep Earth, which aims to visualize the subsurface by digitizing and unifying scattered underground data into accessible 3D maps. Christie describes her path from a toy-inventor upbringing to studying economics and mechanical engineering (robotics) at Claremont and Columbia, then working at SpaceX, interning at the UN and Boeing, moving into early-stage VC in Europe, and joining a fusion startup. Work in carbon removal and geothermal led her to subsurface problems; mining research highlighted boom-bust cycles and long development timelines, motivating a broader focus on faster-feedback markets like water, geothermal, utilities, and construction. She discusses pre-seed funding, network-driven early hires, first paying customers, lessons on pricing and execution, and how investor rejection sharpened the company’s focus.

Chris is back!!  Today we answer the simple question - Why do we see a predictable geologic and topographic progression as we drive from flat plains into mountains?  We use examples from Michigan to Tennessee, the Canadian Rockies, Glacier, the Bighorns, Colorado, and the Appalachians to walk through a common sequence: we start on broad areas of mostly flat-lying sedimentary rocks (sandstones, shales, limestones) deposited in shallow seas, rivers, intertidal settings, and deserts; as we approach the range, we cross subtle, long-wavelength, low-amplitude folds that are often hard to notice without measurements; then we enter the fold-and-thrust belt where anticlines, synclines, and large thrust faults stack sedimentary packages and create dramatic ridges, valleys, and cliff faces (thin-skinned deformation).  We explain how the growing mountain load flexes the plate to form a foreland basin that fills with sediment eroded off the range, typically thickening and coarsening toward the mountains. Farther inboard, we describe how erosion and unloading help exhume deep, high-grade metamorphic “roots” in metamorphic core complexes (gneiss, schist, and other intensely metamorphosed rocks), and how overthickened crust can later relax and extend, aiding exhumation.  We also discuss how some mountain belts preserve suture-related features like ophiolite complexes, while others show subduction-related batholiths (e.g., Sierra Nevada, Idaho Batholith), and we note modern analogs such as the Persian Gulf foreland basin.

On this episode of Planet Geo, we welcome Danielle Bennett—a startup operator with a venture capital background (and not a geoscientist by training) who’s been talking with tons of geologists, hydrogeologists, and engineers while helping build a geoscience-adjacent mapping company at Deep Earth Tech. Danielle shares how growing up with entrepreneur parents (who ran a groundwater-focused engineering firm) shaped her path, why she started a social-impact company in college, and how she moved from corporate finance to FinTech and then into venture capital for about six years.  They dig into what she’s learned from working with the geoscience community—friendly, non-confrontational, and highly opinionated—and why geoscientists may be slower to found startups (a strong perfection/excellence culture and highly localized expertise).  Danielle breaks down “deep tech” in practical terms (asset-heavy and/or science-and-engineering-driven tech), why capital is moving earlier into deep tech, and how VCs are increasingly pulling innovations from universities and incubators. The conversation also gets into which geoscience-adjacent areas feel investable (like shallow geothermal heating/cooling, critical minerals, and renewables) and why groundwater can be harder to fund due to public-agency buying cycles and complex bureaucracy.  Danielle closes by defining key funding terms—bootstrapping, debt financing, private equity, and venture capital—plus what VCs look for (why now, why this team, and scale) and common red flags (unclear messaging, weak grasp of numbers, and unjustified mega-rounds).

In this episode, we bring you a riveting Q&A session with GeoGirl Dr. Rachel Phillips and Dr. Joshua Davies, both experts in geology who explore the mysterious world of banded iron formations (BIFs). We dive deep into what BIFs are, when they formed, and their significance. Josh unpacks the debated origins of these rocks, discussing how they may be the most hotly contested rocks in the geological world due to our limited understanding of their formation process, despite their voluminous presence on Earth. We touch on how BIF layers represent cycles influenced by Milankovitch cycles, and whether microbial activity plays a role in their formation. Josh explains that while BIFs peters out around 1.8 billion years ago, there are unique conditions and debates on secondary processes that impact our current understanding. We humorously explore modern analogs, like weird anoxic lakes, and laugh about how our Earth would need a huge meteorite impact to revert to BIF-forming conditions—a scenario we're not quite rooting for! Finally, we ponder the possibility of extraterrestrial BIFs, symbolizing our endless curiosity about space and deep time. This one’s a dense, iron-packed dive for sure—just like BIFs!

Here is a link to the paper we discuss in this episode: In this episode, we talk about meandering streams.  Why don't rivers flow in straight paths?  As soon as a river flattens out, it begins to meander.  It’s these meanders that manage the energy of the water.  How?  They really do 2 things: 1- they increase the resistance (physics) and 2- they decrease the gradient.  Essentially, the river is changing itself to minimize the energy it expends to maintain a state of equilibrium.  We also get into some detail.  Meanders are not random.  They are directly related to the width of the river and also the radius of the meander curvature.  It's a really cool aspects to river morphology.   We also talk about things that can start meanders.  And finally, we briefly discuss one of geology's more beautiful features - entrenched meanders.  We hope you enjoy!

In this episode of Planet Geo, Chris Bolhuis and Dr. Jesse Reimink dive deep into the geology of the Grand Teton National Park. They cover the park's ancient rock formations, from the Archean gneiss to the granites formed around 2.5 billion years ago. The discussion also explores significant geological events like the Severe and Laramide orogenies, the impact of the Yellowstone Hotspot Track, and the glacial activity that sculpted the dramatic landscapes of the Tetons.  Get access to The Geology of the Grand Tetons on the CampGeo app now - link below!

Hardpan!  Where did this idea for an episode come from?  Chris has  been doing a ton of yard work lately and it’s not uncommon come across a layer when digging a hole that is next to impossible to penetrate. He has to bust out my pick axe to get through it.  It's  Called Hardpan. Really dense layer that often occurs below the topsoil.  Problems:Roots can’t penetrate into the hardpan (Hayden Valley in YNP).  Trees are easily blown over if they can even grow here.Water can’t penetrate so the soil layer above is easily saturated.Safe to say that farmers and gardeners generally don’t like it.Can even cause drainfield failure - creates an impervious layerThese are just a couple of problems - there are more.In this episode, Chris and Jesse do a deep dive into the geology of hardpan.  We hope you enjoy.

Today we really go into the weeds. Jesse and a colleague just published a paper in the journal Nature that proposes a new model for how continents became stable. Stable continents have all the granite at the surface, which contains all the heat producing elements like U and Th and K - elements that decay away. Today, we discuss that paper in detail, and along the way learn a bit about the early Earth, what we know and don't know! Here is a link to the paper, which is open access and can be downloaded by anyone without paying.  Download the CampGeo app now at this link.

Today, Chris and Jesse get into a discussion about Earth’s oldest material.  Earth is 4.568 Billion years old.  First of all, that’s amazing the geochronologists have refined this down to 3 decimal places.  How do we know this?  The oldest grains ever found are 4.38 billion years old.  If that’s the case, then how do we know the Earth is significantly older than that?  Join us as we answer that and many other important questions about Earth’s oldest stuff.   Download the CampGeo app now at this link.

In this episode, we tackle a listener question regarding planning a geology trip for students.  Both Chris and Jesse have quite a bit of experience in planning and executing field excursions for students.  We believe that seeing geology in the field is one of the most powerful learning opportunities for students of all levels.  In our discussion, we talk about the difficulties in convincing the higher-ups that this is actually a good idea.  We also get into some of the struggles in finding excellent teacher resources.  In the end, we get a little philosophical on the importance of getting comfortable with not having all of the answers.  We think that sometimes it's important for students to know that instructors don't know it all and together we can perhaps think about things different and come to new conclusions.  We hope you enjoy.  Download the CampGeo app now at this link.

Join us as we have the honor of interviewing Dr. John Douglas.  Jesse and Chris have been following his research on how the Grand Canyon was actually formed for some time.  We have recently finished our audio-visual book on the Grand Canyon (Link above) and we have a chapter dedicated to the actual cutting of the Canyon.  The answer to this question has been elusive, but there are a few leading theories.  John has been leading the way on the Spillover Theory as a mechanism for carving the young Canyon.  It's a great geologic discussion and we hope you enjoy.

The idea for this episode came from the comment section of a social media post.  It has it's roots in one of the biggest misconceptions in Geology and also Geochronology.  The comment was about radio-carbon dating and how it's been "proven" to be unreliable.  In this episode, Jesse and Chris have a discussion about the "toolbox" for geochronoligists and we also spend a lot of time talking about Uranium to Lead decay.  We hope you enjoy.

In charge of the Nations Rock Collection.  That's a pretty sweet job description.  Join us as we have the honor of interviewing Dr. Mike Ackerson.  In this episode, we certainly get into some detail about igneous petrology.  Mike and Jesse are good friends and have spent some time discussing things that introductory geology classes take for granted.  For instance, there are some questions on the formation of granite.  This might seem ridiculous because this topic is covered in any intro level geology class, but there are some problems. We also talk philosophically about geoscience education and scientific research.  In all, this discussion spans too many areas to summarize here.  We hope you enjoy!   Download the CampGeo app now at this link.

Today, Jesse and Chris discuss the geology of Nickel - The Devil’s Metal.  Surprisingly, Earth’s core has a high percentage of Nickel - 10 to 20% of the core is nickel.  We allow ourselves the luxury of getting into the details on nickel and why the core has so much.  Of all the metals we’ve discussed on the podcast, the geology of nickel is the most complicated.  In addition to discussing the geologic settings that form or concentrate nickel, we also spend some time discussing the history and uses.  We hope you enjoy the discussion.

Today, we have the another great interview - Dr. Anji Shah.   She works for the USGS and has done a lot of work on heavy-mineral sands and critical elements.  In this discussion, we talk about the paleo-environment that could concentrate critical minerals in heavy sands.  Dr. Shah also tells us how "airborn geophysics" is important in looking for mineral deposits over huge areas that are often canopy covered.  We hope you enjoy!

In this episode, Jesse and Chris discuss the geology of asbestos. Really, we cover all things related - history, past uses (some of which are mind boggling),  health issues, and of course the mineralogy. If you want the datail, this episode is for you.

Dr. Adam Simon joins PlanetGeo to discuss many topics.  One of the most interesting topics of discussion is the copper dilemma facing the world.  If we want to transition to green energy like Electric Vehicles, we will face a shortage of copper.  Dr. Simon describes Copper as the artery of a green transition.   However, he's done the math and it doesn't add up.  There isn't enough to make the transition.  We hope you enjoy this extremely informative and entertaining interview.

Today, Chris and Jesse once again revisit the topic of Bowen's Reaction Series.  We've never approached the topic in such a before.  The heart of our discussion centers around 1- What is Bowen's Reaction Series? and 2- How do we approach this highly idealized concept in an introductory class.  How rocks really crystallize in a geologic setting is far more complex than Bowen's Reaction Series.  This can lead to confusion when students progress in their geologic studies when they learn that Bowen's is the whole story (or even the correct story).  We hope you enjoy this technical and philosophical discussion.

Join us as we interview Dr. Steph Mrozek.  Steph is an economic geologist with interests in interests in skarn and porphyry deposits and geochemistry applied to mineral exploration.  In our interview, the discussion turns to degrees in geoscience and educational pursuits.  We’ve received a number of questions from listeners about what degree to pursue and how far to go.  Steph offers unique perspectives on this topic that many of our listeners will find very useful.  Then our discussion turns to a niche geologic topic - Skarns.  Jesse and I learned a ton.  We (Jesse and I) have some personal experience with Skarn deposits, but Steph is the expert in the room for sure. In the end, we have an in depth discussion about a career in exploration and mining geology.  This episode has so much to offer.  Listeners will learn about a topic that many aren’t familiar with and will also learn about the life and times of an exploration geologist.  We know you will enjoy this episode.

Join Chris and Jesse as we tackle questions about the Grand Canyon.  A 4th grade class, Bronx Little School, reached out in a letter with a list of fantastic questions.  We knew right away we wanted to make an episode about this.  These questions, and our responses, provide a great introduction to the geology of The Grand Canyon.  Below are the questions - asked and answered: 1. How deep is the Grand Canyon? 2- Why are the rocks orange, red, and black?  How were the rocks made? 3- Why is the Grand Canyon so steep? 4- How old is each layer in the Grand Canyon? 5- They didn't ask this question, but Jesse and I couldn't resist.  So we posed the question: How did the Grand Canyon get cut?  Maybe one of these awesome students will find the answer. We hope you all enjoy learning a little more about one of the Natural Wonders of the World.  Cheers Download the CampGeo app now at this link.

Today, we re-visit one our earliest episodes that we recorded when this whole thing began.  We've decided to do a small series on Earth's climate and feel that this is the best kickoff point for that topic.   We begin by discussing the forgotten history of climate science.  This is important because we have known the physics of greenhouse gases for over 200 years.  This pre-dates excessive fossil fuel consumption and any thought of political ideology around climate change.  We talk about following the radiation from the sun and the change that takes place when certain photons are absorbed at the Earth's surface.  That change in energy is what gets absorbed by the various greenhouse gases.  We round out the discussion by talking about several of the important gases and why carbon dioxide is the "big dog" in the discussion.  We hope you enjoy!

Today, Jesse and Chris tackle the topic of the Slow Carbon Cycle.  We've been talking about this for a while now.  This is a very complicate cycle that involves many variables.  In this episode, we work through some scenarios such as the Himalayan uplift and plug them into the Carbon Cycle.  It's a little bit of mental gymnastics.  The ingredients for the Carbon Cycle to operate are freshly exposed rock, water (both in the oceans and the atmosphere), and plate tectonics.  If one of these variables is taken out, the Carbon Cycle ceases.   Join us in this fun and interesting discussion.

In this episode, we tackle the issue of infiltration capacity.  The idea came to us in the form of a listener question due to recent events.  Infiltration capacity is simply a way of describing the ability of soil and regolith to soak up water during storm events that drop a lot of rain in a short period of time.  There are several variables that must be accounted for in describing the infiltration capacity for a given area.  Humans have also caused a significant change related to this topic.  Join us in this fun conversation that has a lot of relevance in todays world.

Today, Jesse and Chris discuss the distinction between sinkholes and karst topography.  There is a surprisingly large portion of the U.S. that has potential to be affected by karst.  It is also extremely important as a source of drinking water.  We also discuss the distinction between the technical definition of karst and what is called pseudokarst.  Below is a link to the article and diagram we allude to in the show.  We hope you enjoy. https://www.frontiersin.org/articles/10.3389/feart.2023.1207689/full Download the CampGeo app now at this link.

We get a bit reflective today and discuss the importance of Geoscience to society - and how it has changed in the last three years. Jesse recently went to a conference on economic mining and came away newly excited.  If the world is going to make the energy transition, certain elements are critical in allowing us to meet that demand.  Today, we talk about the issues surrounding the energy transition and how geoscientists are playing an integral role (and will continue to do so) in society.  We hope you enjoy!

Today, we are talking about the process of making petrified wood.  Basically, wood has to be quickly buried in a wet setting where the water is also saturated in certain minerals - usually silica.  Also, there must be little oxygen present or oxidation reactions have to occur to use up all of the available oxygen.  This prevents the wood from getting eaten by decomposers.  We will also get into the geologic settings where this is likely to occur. Finally, we talk a little about how we come up with ages of petrified wood and use this to kick off a series on Geochronology.  Enjoy! Download the CampGeo app now at this link.

Today, we talk about all things soil creep.  Have you ever been on a steep slope and seen bent or curved trees, slanted fence posts, slanted headstones or signs?  Look closely and you can often see the surface has a rippled appearance.  Soil Creep is a form of what we call Mass Wasting in Geology.  Mud flows, avalanche, and rockfall are also examples of Mass Wasting.  Creep just happens very, very slowly.  Join us and learn how this fascinating process works!

Here is a link to the paper we discuss in this episode: In this episode, we talk about meandering streams.  Why don't rivers flow in straight paths?  As soon as a river flattens out, it begins to meander.  It’s these meanders that manage the energy of the water.  How?  They really do 2 things: 1- they increase the resistance (physics) and 2- they decrease the gradient.  Essentially, the river is changing itself to minimize the energy it expends to maintain a state of equilibrium.  We also get into some detail.  Meanders are not random.  They are directly related to the width of the river and also the radius of the meander curvature.  It's a really cool aspects to river morphology.   We also talk about things that can start meanders.  And finally, we briefly discuss one of geology's more beautiful features - entrenched meanders.  We hope you enjoy!

In this episode, we interview author Andrew Alden.  He wrote Deep Oakland: How Geology Shaped a City.  This book is a wonderful read and it offers a unique lens in which to view a city.  Jesse and Chris both think that this idea should become a series - much like the Roadside Geology series.   Andrew talks about his motivation for the monumental task.  The 1989 Loma Prieta earthquake that shook the city of San Francisco and kind of woke him up to the idea.  Deep Oakland is an intricate story involving the intersection of geology and humanity.  Specifically, geology determined early decisions in the planning of Oakland.

Today, we answer some listener questions in what we call "office hours".  We each chose a question for the other to answer.  We did not know what questions we would be asked so our answers were on the fly.  Jesse asks Chris a question from Joyce (his mom) about a new word that she needs to know.  Chris chose paleomagnetism.  Then, Jesse asked a more serious question regarding the potential for humans to influence the chemistry of magma in the geologic future. Chris chose a question from Ava regarding the origin of slab pull as a mechanism for plate tectonics.  We hope you enjoy! Like, Subscribe, and leave us a Rating!

In this episode, we take on the topic of Barrier Islands.  This is a very relevant topic because recent storms have devastated some of these Islands.  The intersection between geology and humans is always an interesting topic.   Barrier Islands need three things: Sand supplyBroad sloping coastlineWaves/tides/currents must be strong enough to move sand (high-ish energy)Waves must be dominant In this context we discuss the 3 ways in which they form.  Each Island has it's own unique story and all 3 scenarios play a role.   We also discuss the function of Barrier Islands in terms of protecting the mainland and also unique biological habitats.

Learn all the basics of geology in our new conversational textbook - campGEO! Available here: geo.campcourses.com In this episode, we tackle the issue of when plate tectonics started on Earth and why this is an important question.  This is a large part of Jesse's research so he has a lot to say.  In order to address this question, we first discuss some parameters and what defines plate tectonics. We also get into some detail by discussing some variations on the plate tectonics model:  Things like sagduction, squishy-lid tectonics, stagnant lid tectonics and episodic tectonics to name a few.   We hope you enjoy!

Rare Earth Elements are a huge topic in mining and geology now, and in technology. The most important at the moment is Neodymium (Nd) and it is also really important for geology research.  Let’s cover the basics. In this episode, we discuss Neodymium in two broad concepts: 1- the importance for society and geological research, and 2- the geology of Neodymium. Some example of the societal importance are that these are the strongest commercially available magnets, they are used in electric and hybrid vehicle motors - the two motors in a Tesla that make it go fast!  Toyota Prius said to contain ~ 1kg of Nd in it’s motor, it's used in wind turbines, Buckeyballs (banned because kids kept swallowing them, they're use in MRI machines.  These are just a few examples.

Learn all the basics of geology in our new conversational textbook - campGEO! Available here: geo.campcourses.com One day, I (Chris) walked into class and announced that we were beginning plate tectonics.  I was so excited to begin teaching this content.  The response from my students was not at all what I expected.  They let me know that they had all the plate tectonics they could handle in middle school and there wasn't anything left to learn.  They knew the 3 basic types of plate boundaries (kind of) - divergent, convergent, and the T-one.  I then started asking deeper level questions that tested their ability to apply this huge theory to make sense of the world around them. During lunch that day, I began writing a series of questions about the unifying theory of plate tectonics.  Needless to say, their understanding was skin deep and that's totally Okay.  I wanted to show that we can take a basic understanding and use it to make so much more sense of our world.  That "event" gave me the idea to do a series on PlanetGeo covering a deep dive into plate tectonics.  Jesse was not easy to convince.  He felt like it was too massive.  Anyway, I won and here comes the series.  In this episode, we answer the following questions: 1.  How does plate tectonics explain the formation of basalt? 2. How does plate tectonics explain the formation of andesite? 3. How does plate tectonics explain the formation of granite? We hope you enjoy!

Learn all the basics of geology in our new conversational textbook - campGEO! Available here: geo.campcourses.com In this episode, we tackle the confusing industry of "granite" countertops.  It's confusing because it seems as though all rock countertops are called "granite".  However, to a geologist, granite is a very specific type of rock and only a small percentage of countertops are actually granite.   There are maybe 5 or so major rock types that are all found in the "granite" countertop category.  We spend some time talking about each major type: Marble - this might be named accurately actually in most places.  Is it very white with no distinct grains showing?  Then it is probably marble.  Especially if it has long dark wavys streaksGranite - there is some real granite in there!  Does it have pink, white, grey, and a few black flecks in it?  Most of the grains are smaller than your fingernail? Then it may actually be granite.  Can be white - no pink, too.  Has to have some black flecks and some gray too. Pegmatite - Does it have really really large grains?  The size of your finger?  Grey, white, black, with crazy textures in between them?  It might be a pegmatiteSchist/gneiss - does it have a definite texture and pattern in one direction?  Are their little waves of light and dark wavy patterns? Are there big deep purple garnets in it or blue flakes?  What about dark and light bands with an overall darker color?  It could be gneiss or schist. Conglomerate - does it have a bunch of round or oblong grains in it of a variety of colors?  Could be a conglomerate - these are spectacular. There are others to be sure.  These are just the most common.We also talk about another type that is growing in popularity - Quartz counters.  They aren't actually quartz though.  We like this option a lot because it's a green product.  No rock was mined for the specific purpose of making countertops.  Quartz countertops are a form of engineered stone, made from ground-up particles of stone bound together with plastic resins.  About 90% of the material is Crushed up waste granite, marble, and natural stone or recycled industrial wastes such as ceramic, silica, glass, mirrors, etc. We hope you enjoy! —————————————————— Instagram: @planetgeocast Twitter: @planetgeocast Facebook: @planetgeocast Email: [email protected] Website: https://planetgeocast.com/ Download the CampGeo app now at this link.

Learn all the basics of geology in our new conversational textbook - campGEO!  Available here: geo.campcourses.com In this episode, we dive into a very important topic that will play an increasing role in the climate change crisis.  Carbon (CO2) capture and storage (CCS) is a big geoscience problem, and a possible solution to climate change.  But, we need to understand these two terms well - it’s all about making rocks! The oceans capture carbon for us, but we want to help this process along.  In order to do that, we need to find ways to concentrate the Carbon because it's in such a low overall concentration in the atmosphere.  We discuss some of the ways companies are trying to speed up the concentration process. Once the Carbon is captured, we need to find ways to store it.  Rocks such as limestone in the ocean is a natural way for Carbon storage.  Again, we discuss some of the creative ways companies are researching to effectively store the captured carbon.  We hope you enjoy our discussion on the very important topic. —————————————————— Instagram: @planetgeocast Twitter: @planetgeocast Facebook: @planetgeocast Email: [email protected] Website: https://planetgeocast.com/ Download the CampGeo app now at this link.

Available here: geo.campcourses.com This is a link to the video of the Quick Clay Slide at Dissa video Dr. Alley references. This shows what can also happen to a glacier when it loses it's toe-hold as described in this episode. Dr. Richard Alley is a renowned glaciologist and paleoclimate scientist.  He is also widely regarded as one of the best professors at Penn State University.  Below is a list of his impressive credentials: National Academy of SciencesForeign Member of the Royal SocietyEvan Pugh University ProfessorshipPenn State’s top teaching awardPresidential Young Investigator AwardEarth - the Operator’s Manual - Briefed senators, international legislators, and a sitting US Vice PresidentPublished an unbelievable >310 papers/books/etcJoin us as we discuss climate change, glaciers, and sea level.  Much of his current research is on a Western Antarctic glacier called Thwaites Glacier.  It's been dubbed the doomsday glacier because of its likely impact on sea level.  Alley is a gifted speaker and uses  incredible analogies to paint a vivid picture.  Another big part of the discussion is how Carbon is the thermostat control knob for our atmosphere.  We hope you enjoy the discussion.  We did! —————————————————— Instagram: @planetgeocast Twitter: @planetgeocast Facebook: @planetgeocast Email: [email protected] Website: https://planetgeocast.com/ Download the CampGeo app now at this link.

Learn all the basics of geology in our new conversational textbook - campGEO! Available here: geo.campcourses.com 536 AD was not a good year to be to be a human - especially in Eastern Europe.  Below are some written descriptions of what it was like: Michael the Syrian, wrote: "[T]he sun became dark and its darkness lasted for one and a half years [...] Each day it shone for about four hours and still this light was only a feeble shadow [...] the fruits did not ripen and the wine tasted like sour grapes."A prefect of Italy at the time, wrote: "so we have had a winter without storms, spring without mildness, summer without heat."A roman politician wrote: “the sun had a buish color, the moon lost its luster and the seasons seem to be jumbled up together.Global temperatures fell by 2.5 degrees C (5 degrees F) on average.  The culprit was an Icelandic volcano that began eruption in early 536 AD.  This was punctuated by another eruption in 540, the bubonic plague in 541, and another eruption in 547 to round out one of the worst decades to be alive on Earth.  All of these events caused a combined effect that took the planet over a hundred years to recover.   In this episode, we discuss a little about the geology of Icelandic volcanoes and why they are so diverse.  However, the main focus is on the process of scientific discovery.  We dive into ice core analysis and tree ring data that helped researchers piece together the puzzle. Join Jesse and Chris as we discuss what might have been the worst year, decade, or century to be a human in modern times.  —————————————————— Instagram: @planetgeocast Twitter: @planetgeocast Facebook: @planetgeocast Email: [email protected] Website: https://planetgeocast.com/ Download the CampGeo app now at this link.

Learn all the basics of geology in our new conversational textbook - campGEO! Available here: geo.campcourses.com After a long break from recording, Chris and Jesse return to our studios to discuss our extremely busy summer.  Jesse recaps his trip to Hawaii where he saw some amazing geology.  He also talks about teaching field camp in Idaho to some of the Penn State undergrads.  His favorite though, was continuing his field research in the Northwest Territories of Canada.  He and his PhD student collected over 1,000 pounds of rocks.  When asked about his favorite rocks seen this summer, Jesse didn't hesitate - the ancient rocks in Northern Canada.  The toothpaste rocks won out over the much younger pahoehoe rocks of Hawaii. Chris talked about taking 26 high school seniors out West for 3 weeks on the field course that he teaches.  They went to the South Dakota Badlands, Black Hills, Devils Tower, Grand Tetons, Yellowstone, and Glacier National Park.  The floods that ravaged Yellowstone in early June didn't prevent the students from learning about the incredible geology of Yellowstone.  Following this, Chris returned to the West with his family to hike and climb.  They went to the flatirons of Red Rocks and then on to Long's Peak.  The Long's Peak granite was easily his favorite rock of the summer.  The rock is interesting because it is a porphyritic granite.  The huge phenocrysts are peculiar because they are not randomly oriented.  Instead, they are aligned in a preferred direction which is a topic of current research.  After leaving Colorado, Chris and family spent the next two weeks banging around in the Tetons. We wrap up the episode by discussing a couple of mineral pairs that can be confusing to identify in the field.  Join us as we have a casual conversation about some incredible geology!

Learn all the basics of geology in our new conversational textbook - campGEO! Available here: geo.campcourses.com Sand comes from chemical and/or physical weathering of rocks, and is critically important to our society!  Most sand formation begins in the soil - soil has water to further break down the pieces.

Learn all the basics of geology in our new conversational textbook - campGEO! Available here: geo.campcourses.com People often wonder, why can't we date diamonds?  Today, we answer that!  Here, we talk through the basics of Carbon Dating, also called RadioCarbon Dating!  Radiocarbon is an awesome technique that also has some really common misconceptions about it.  We go through the basics of this amazing method, with great analogies as usual, and we cover all those misconceptions! Carbon dating is a great tool for dating things that were once alive.  However, the half-life of Carbon-14 is 5,730 years.  This means that after something has been dead for over 50,000 years, there is virtually no Carbon-14 left to date.  This is why Carbon dating can't be used on dinosaurs (or diamonds) - no Carbon-14 remains.   Also, Carbon dating is not an appropriate tool for dating most rocks for two reasons.  First, most rocks don't have abundant Carbon-14 when they formed.  Second, most rocks are very, very old.  Fortunately, there are many other appropriate tools that scientists can use to date rocks.  Jesse is definitely the expert in the room in this discussion.  His research involves different dating methods that he's been using for years.  We hope you enjoy the discussion. —————————————————— Instagram: @planetgeocast Twitter: @planetgeocast Facebook: @planetgeocast Email: [email protected] Website: https://planetgeocast.com/ Download the CampGeo app now at this link.

His work has appeared in National Geographic, The New York Times, The Atlantic, Scientific American, Gizmodo, Atlas Obscura and elsewhere. He trained as a volcanologist, earning a doctorate in the subject, but then realized that telling people stories of spectacular eruptions and off-world scientific shenanigans brought him more joy than academia ever could. His upcoming book — Super Volcanoes: What They Reveal about Earth and the Worlds Beyond is out now - go buy a copy! I must admit, it took Jesse and I a while to realize that the book is called Super Volcanoes - two words.  In other words, all volcanoes are super.  Most volcanologists strongly dislike the term Supervolcanoes - one word, that is typically used to describe Yellowstone National Park.   Robin has a huge personality which made for a very fun interview.  We talked about Hawaii, Yellowstone, deep ocean volcanoes, Tonga, and Marie Tharp to name just a few.  Tune in to get all the details.  You won't be disappointed. —————————————————— Instagram: @planetgeocast Twitter: @planetgeocast Facebook: @planetgeocast Email: [email protected] Website: https://planetgeocast.buzzsprout.com/  Download the CampGeo app now at this link.
