Classification of Igneous Rocks Classification.ppt

John Winter, Department of Geology

This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers classification of phaneritic igneous rocks, gabbroic rocks, ultramafic rocks, pyroclastic rocks and volcanic rocks using triangular diagrams, and classification of igneous rocks based on total alkalis vs. silica. This resource is part of the Teaching Petrology collection.

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.
