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. We now hav ..read more

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 philosophicall ..read more

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. Jesse goes off the deep end a little as he nerds out on some geochemistry.  We hope you enjoy.  We now have a live Mobile App for iOS and Android.

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 t ..read more
