This course delves into the intersection of thermodynamics and petrology, applying fundamental principles of thermodynamics to understand the behavior of Earth materials and processes. By the end of the course, students emerge with a deep understanding of thermodynamics as applied to petrological systems, equipped with the analytical skills and knowledge necessary to investigate and interpret a wide range of geological phenomena. This interdisciplinary approach bridges the gap between thermodynamics and Earth sciences, providing students with a valuable perspective on the behavior of Earth materials and processes.
