Course Text: Petrology by H. Blatt, R. J. Tracey, and B. E. Owens (2006)
Lab Text: Petrography of Igneous and Metamorphic Rocks by A. R. Philpotts (1989) + CD
Two 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 own a hand lens, please purchase one from Ms. Sarah Esh before coming to lab on Tuesday, January 22.
Class convenes in P-111 at 9:00 AM; Lab convenes in P-111 on Tuesday beginning 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 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.
Examination Schedule: Monday, February 18, 2008 and Friday, March 28, 2008.
The two articles listed below summarize topics that permeate igneous petrology. They will serve as your most comprehensive reviews for these two areas. You will find it most productive to read them the first time for general concepts and the second time for more of the details. These two papers are from the volume entitled:
Encyclopedia of Volcanoes, H. Sigurdsson, editor, which was published by Academic Press in 2000.
1) Plate Tectonics and Volcanism, M.R. Perfit and J.P. Davidson, pp. 89-113.
2) Composition of Magmas, N. Rogers and C. Hawkesworth, pp. 115-131.

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.
