Episode 39

Hold on to your seats because if you love rocks, QAPF diagrams, or simply nerding out, this episode is for you as we take a deep dive into the magnificent world of basalts. Basalts are simply aphanitic extrusive igneous rocks formed from the rapid cooling of low-viscosity lavas rich in magnesium and iron exposed at or near the surface of rocky planets or moons. Nearly 90% of all volcanic rocks on Earth are basalt. From tholeiitic basalts to alkali basalts to mid-ocean ridge basalts to the basalts of Hawaii & Iceland, nothing is off-limits for us. We have fun facts galore, poems, a mineral minute, lots of giggles, and tangents sprinkled throughout. We then talk about Mr. Baggin’s trip to the Hawaiian Islands on the back half, followed by James the Geologist’s trip to the recording studio. Rock Opera may or may not be at 1:17:01, but you will just have to listen for yourself to find out.

Until next time be cool, stay tuned, and keep it on the rocks!
