Intro to Sediments - Geology 101: Sediments Part 1
First, some news. The Roadside Geology of Colorado is now an audiobook on the Camp Geo mobile app, produced in partnership with the Geological Society of America. If you've ever driven across the country with a stack of Roadside Geology books riding shotgun (Chris and Jesse have, many times), this is that experience in your ears, with the images that go with it. It's the first title in what we hope becomes a whole series, so try it out, tell your friends, and let us know which state you'd lik...

How to Identify a Mineral. Geology 101: Minerals Part 4
Chris's college mineralogy lab final was 20 specimens, and one of them was a quartz crystal his professor had dipped in graphite. The luster was off, the color was off, and Chris got it wrong even though every other property said quartz. That one exam question shows why mineral ID is hard and why you need a system. This episode lays out that system. We finish the minerals chapter of the Camp Geo audio textbook with polymorphs, which are minerals with the same chemical composition but differen...

The Rock-Forming Minerals. Geology 101: Minerals Part 3
There are roughly 7,000 known minerals on Earth. You need to know about ten of them. In the third installment of the Camp Geo Intro to Minerals series, Chris and Jesse finish the minerals chapter by working through the rock-forming minerals — the short list that makes up the overwhelming majority of the rocks in Earth's crust — and by explaining where minerals actually come from in the first place. Before the top-ten list, they step outside the silicates. Just as the silica tetrahedron define...

The Silicates. Geology 101: Minerals Part 2
Ask an intro geology class what the most abundant element in the crust is and, year after year, the answer comes back "carbon." It doesn't make the top eight. That gap between what feels right and what the planet is actually made of is where this lesson lives. Chapter 2 of the Camp Geo audio textbook starts with the layered Earth — crust, mantle, and core — and why Chris's peanut M&M (with a caramel injection for the liquid outer core) beats Jesse's apple. Then the chemistry of each layer...

What is a Mineral? Geology 101: Minerals Part 1
Ask a room full of intro geology students whether a snowflake is a mineral and almost every hand says no. Ask why, and someone will tell you it's because no two snowflakes are alike. Chris Bolhuis has been asking that question for 25 years — he asked it of a young Jesse Reimink sitting in his high school classroom — and the answer is the whole point of this lesson. It's been a while since we've released an episode on the Planet Geo feed, and there's more coming (plus a few projects we can't w...

Lithium 101 with Joe Lowry: Brines, Pegmatites, DLE, and the Smackover

He spent 35 years in the industry — including years in Japan and China — and for a stretch in the 1990s he personally controlled essentially a...

How to Find Copper — Dr. Tim Ireland, First Quantum
There's a photo on Tim Ireland's Google Scholar profile of a toddler standing on the floor of an open pit gold mine in Australia's Northern Territory, wearing a hard hat and — because it was the early 1980s — flip flops. That toddler is now the Principal Geologist for Exploration at **First Quantum Minerals**, one of the world's major copper producers, and in this episode Jesse sits down with him to talk about how mineral exploration actually works. Tim grew up with two geologist fathers, b...
