Intended as an introduction to Geochemistry for Geology majors in their senior year or first year of graduate work. Designed to show students how to use chemical principles in solving geological problems, this text emphasizes a quantitative approach to problem solving and demonstrates how chemical principles control geologic processes in atomic and large-scale environments.
