Course Text: Principles of Igneous and Metamorphic Petrology, 2nd edition by John Winter (2010)
Lab Texts: Petrography of Igneous and Metamorphic Rocks by A. R. Philpotts (1989) + CD and
Simon & Schuster’s Guide to Rocks and Minerals
Several copies of Basalts and Phase Diagrams (BPD-1) by S. A. Morse are kept in P-111. Consult them for various assigned readings.
Please Note: If you do not already own a hand lens, please purchase one from Ms. Diane Kaydk before coming to lab on Tuesday January 17, 2012.
Class and Lab both convene in Hackman 111: Lab#1 begins on Tuesday January 17 starting at 1:30 PM.
Attendance Policy: Class participation is an important aspect of this class. You need to be in class to participate so naturally I expect to see you in class virtually everyday.
Grading: 2 hour exams (15% each) + the final exam (20%) + class participation (10%) + 20% is the rock project and that includes an oral presentation + paper, and the last 20% of your final grade is the lab portion of course and that includes the two lab quizzes + weekly assignments.

Please Note: The first two chapters of Philpotts’s Petrography lab-book are a nice review of the basics of optical mineralogy. Know this material. Chapter 3 (pp. 25-92) will prove essential for your lab work in this course. You are responsible for the mineral and formulas listed on pages 26 through 29. Use Simon & Schuster’s Guide to
Mineral identification for your work on hand samples and your project sample.
