Igneous Petrology Handouts Archive

Most of these handouts, unless otherwise indicated, take somewhere between 20 minutes and 1 hour to complete in small groups, with the instructor circulating to answer questions.

Many of the handouts rely heavily on material from Winter (2001) An Introduction to Igneous and Metamorphic Petrology, as well as thermodynamics handouts from John Winter's website: http://www.whitman.edu/geology/winter/. The REE diagram handout uses a figure from Henderson (1982) Inorganic Geochemistry. The melt viscosity exercise is based on a paper by Baker et al., 2004, Journal of Geoscience Education, 52, 363-367.
