A good update for a fifty year geologist
Format: Hardcover
I wanted an update on plate tectonics as I was a geologist for 50 years and it was a theory back when I was in school particularly on mountain building I have been impressed so far I am about half way through the book and the book does a fine job of laying a solid foundation of physics and geochemistry that are the basics for the remainder of the book

An excellent introduction to plate tectonics
Format: Kindle
My rating is 4.5 stars. I dinged the book because I wanted more about geobiological evidence for and against plate tectonics, and because it didn't mention other global tectonics, such as single-lid tectonics. Read Robert Stern's article in the May 2025 issue of the GSA bulletin.
