Glad to have you studying with me! I have more content in the works and I hope you'll enjoy it. For those that are interested, the best textbook out there is this one: https://amzn.to/47VNed8. However, it's a little old now (two of the authors have passed away) and if you prefer a newer textbook, I would recommend this one: https://amzn.to/45UFDcR For other introductory geology lectures:    • Introduction to Geology   This video is my lecture on sedimentary rocks. It covers the textures and origins of sedimentary rocks, the minerals frequently encountered, and the depositional environments. I hope you enjoy it! This video is also closed captioned.
