Modal vs Norm Mineralogy, Major vs Trace Elements, and Indices - Igneous Petrology

This course examines the chemistry of igneous rocks, including modal and normative mineralogy, major-element indices, Harker diagrams, trace elements, and partition coefficients. It applies these concepts to magma differentiation and the cooling and crystallization history of rocks.
