IGNEOUS PETROLOGY

Prerequisites & course information

Requisites: Graduate/professional standing Course Designation: Grad 50% - Counts toward 50% graduate coursework requirement Repeatable for Credit: No Last Taught: Fall 2025 Learning Outcomes: 1. Explain how magmas are formed by partial melting of rocks within the Earth, and how magmas are modified by differentiation processes during storage and transit within the earth. Audience: Graduate 2. Explain how the products of volcanism on earth, including lava flows and pyroclastic deposits, provide windows into the processes of partial melting and magma differentiation. Audience: Graduate 3. Utilize the many tools used to quantify the processes of partial melting and magma differentiation, including thermodynamic modeling of phase equilibria, trace element geochemistry of minerals, melts, and rocks, isotope geochemistry of minerals, melts, and rocks, and diffusion chronology of igneous minerals. Audience: Graduate 4. Explain how magmas are formed and modified in different ways depending on the plate tectonic setting, including at mid-ocean ridges, subduction zones, and continental rifts. Audience: Graduate 5. Interpret what the solidified products of igneous activity on earth are, and how to distinguish processes of formation from the textures and minerals comprising them.
