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

This lecture video covers how magmas form, what makes different types of magma, and their relation ship to lavas and mineral deposits. It's been arranged for anyone who wants a deeper knowledge of lavas and magmas. I hope you enjoy it! Closed captioned.
