This set of lecture notes discusses the occurrence and tectonic settings of igneous rocks near convergent plate margins. A discussion of petrography includes major element composition, calc-alkaline trends in ternary diagrams, trace element variations, isotopes to distinguish magma sources, and the origin of igneous rocks at convergent margins. The lecture notes include helpful illustrations, maps and phase diagrams. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
Part of the Cutting Edge collection. The NAGT/DLESE On the Cutting Edge project helps geoscience faculty stay up-to-date with both geoscience research and teaching methods.
