Add to ORKGThis web site is maintained by John Winter of Whitman College, and contains 31 PowerPoint presentations for an igneous and metamorphic petrology course. The course and the lectures are keyed to his text, An Introduction to Igneous and Metamorphic Petrology. The PowerPoint presentations are organized by chapter and contain many maps, graphs and illustrations. Each chapter is a separate PowerPoint file that can be downloaded and modified to suit the user's needs. In addition, the website includes a link to a short tutorial on how to use CSPACE, a program used to balance equations, and a link to an Excel spreadsheet used to calculate CIPW norms. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/...
