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 kn...

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 ab...

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 go...

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 ...

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...

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 mig...

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 concent...

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...

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.

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...

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 c...

Today is our latest episode in our series on climate.  Jesse and Chris discuss the meaning of "Hard Water".  Chris and Jesse both have hard water at our houses and we talk about how that happens.  We wrap up this episode by talking about how the topic of hard water fits into our series and climate.  We hope you enjoy!

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 o...

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 ...

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...
