What moves the continents, creates mountains, swallows up the sea floor, makes volcanoes erupt, triggers earthquakes, and imprints ancient climates into the rocks? Oliver Strimpel, a former astrophysicist and museum director asks leading researchers to divulge what they have discovered and how they did it.

We know that most magma originates in the Earth’s mantle. As it pushes up through the many kilometers of lithosphere to the surface, it pauses in one or more magma chambers or partially melted mush zones for periods of up to a few millennia before erupting. But while we have seismic evidence and models and support this picture, we have not hitherto…

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…

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 o…

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 t…

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 h…

At roughly 15-25-million-year intervals since the Archean, huge volumes of lava have spewed onto the Earth’s surface. These form the large igneous provinces, which are called flood basalts when they occur on continents. As Richard Ernst explains in the podcast, the eruption of a large igneous province can initiate the rifting of continents, disrupt…

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 a…

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. Fo…

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 …

From dinosaurs to rhinos to bugs, things used to get a whole lot bigger than they seem to today. In this episode we talk all about evolutionary constraints, the narrow set of bumper bars enforced on us by biology. CW: Body fluids. Using the term bug incorrectly (sorry entomologists). Cursing.

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 miner…

It’s time to be more afraid of seals, everyone. And hyenas. And tigers. And… birds? And big crocodiles. Really, the deeper you go into human history, the longer that list of fears gets – and on this episode, we go real, real deep. CW: death, dead bodies, being hunted, cannibalism.

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. Jesse goes off the deep end a little as he nerds out on some geochemistry. We hope you enjoy. We n…

Trace fossils are an incredible resource to understand behavior… even behavior those animals wish maybe there wasn’t a record of. From the results of terrible food poisoning to the fossil equivalent of a xeroxed buttocks, trace fossils record some animals’ most humiliating moments. CW: Everything in the title, cursing, stomach stones (bezoars)…

Perhaps as many as five times over the course of Earth history, most of the continents gathered together to form a supercontinent. The supercontinents lasted on the order of a hundred million years before breaking apart and dispersing the continents. For decades, we theorized that this cycle of amalgamation and breakup was caused by near-surface te…

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…

Did you know that technically, the name ‘dinosaur’ is a rebrand? The original name was a lot more… wrinkly. In this episode we discuss how to name fossils and bring up the funniest fossil names we could find. CW: Cursing. Discussion of European colonization and Native Americans. Many references to genitalia.…

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 …

Asteroids, volcanoes, and sex lakes – in this episode we discuss the varied and sometimes hilarious hypotheses of why animals have gone extinct. CW: Extinctions/animal death, toxic shock syndrome, menstruation, serial killers, suicide in reference to having to do geochronology. Referring to non-avian dinosaurs as just dinosaurs.…

The Earth’s tectonic plates float on top of the ductile portion of the Earth’s mantle called the asthenosphere. The properties of the asthenosphere, in particular its viscosity, are thought to play a key role in determining how plates move, subduct, and how melt is produced and accumulates. We would like to know what the viscosity of the the asthen…

While usually it’s just the hard bits that fossilize, occasionally the fossil record can preserve things like skin, organs, blood and more. This episode talks about what happens when soft tissue fossilizes, and what weird things scientists have done upon finding it.

Sometimes paleontology is awe-inspiring. Sometimes it’s gross and hilarious. This episode is at the weird epicenter of all of those things, because it turns out the best preserved fossil sturgeons are found up the rear end of duck-billed dinosaurs.

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 ove…

In many countries, nuclear power is a significant part of the energy mix being planned as part of the drive to achieve net-zero greenhouse-gas emissions. This means that we will be producing a lot more radioactive waste, some of it with half-lives that approach geological timescales, which are orders of magnitude greater than timescales associated …

We have learned a great deal about the geology of the Moon from remote sensing instruments aboard lunar orbiters, from robot landers, from the Apollo landings, and from samples returned to the Earth by Apollo and robot landings.

At the core of Earth’s geological thermostat is the dissolution of silicate minerals in the presence of atmospheric carbon dioxide and liquid water. But at large scales, the effectiveness and temperature sensitivity of this reaction depends on geomorphological, climatic, and tectonic factors that vary greatly from place to place. As described in th…
