Instructor: Prof. James Mills E-mail: jmills@depauw.edu Office: JSC 214 Phone: 658-4669 or 658-4654 Office Hours : 11:30-12:30 am MWF or by appointment Required Texts: An Introduction to Igneous and Metamorphic Petrology

Winter, J.D., 2001, Prentice Hall Publishers A Color Atlas of Rocks and Minerals in Thin Section MacKenzie, W.S., and Adams, A.E., 1994, J. Wiley and Sons Class Times: Lecture, JSC 226, 10:10-11:10 MWF Lab, JSC 226, 10-11:50 am Th Attendance: Regular attendance is required for all lectures and labs. Laboratory: Labs will be assigned on a weekly basis and will be due at the beginning of the

following lab period. Late labs will be downgraded 20% for every day they are late. Failure to turn in three or more labs will result in an ‘F’ in the course regardless of your performance on exams, homework and projects.

Laboratory Equipment: Please bring to lab the following materials: Coloring pencils, an

inexpensive compass for drawing circles, hand lens (10x), calculator, and your optics book for reference.

Homework, Quizzes: There will be several homework assignments over the course of the

semester. Late homework will not be accepted. Over the course of the semester, I will give several unannounced quizzes on the reading.

Projects: At least twice during the semester we may visit local outcrops to examine and collect

specimens for study in the lab. These trips and associated exercises will be included in your grade for the course.

Field Trip: A trip to examine the Precambrian geology of Missouri will be scheduled based on

your schedules (i.e. Spring Break?). You are strongly encouraged to participate on this trip.

Grade Scale: Grades will be determined based on the following criteria: Exams (3) 30% A 100-93% B- 82-80% D+ 69-67% Final Exam 20% A- 92-90% C+ 79-77% D 66-63% Labs 35% B+ 89-87% C 76-73% D- 62-60% Homework, 15% B 86-83% C- 72-70% F <60% Projects, Quizzes Academic Integrity: Any act that places a student in unfair advantage with respect to the rest of the class will be treated according to the University procedures outlined in the Student Handbook.
