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!We now have a live Mobile App for iOS and And...

Some Rocks You SHOULD Know - Metamorphism and Plate Tectonics

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 do...

When Continents Became Stable

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.  ...

Earth's Oldest Stuff

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 str...
