1 GEOS 320 PETROLOGY Instructor: Prof. Jim Mills Office: JSC 214 Phone: or Office Hours: 10:20-11:30 MWF or by appointment Required Texts: Essentials of Igneous and Metamorphic Petrology, 2013, Frost B.R. and Frost C.D., Cambridge University Press, ISBN-13: , 336 p. Petrography of Igneous and Metamorphic Rocks, 2003, Philpotts, A., Waveland Press Inc., ISBN , 192 p. Class Times: Lecture, JSC 226, 12:30-1:30 MWF: Lab, JSC 226, 12:40-3:30 pm Tuesday 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), and calculator. Homework, Quizzes: There will be several homework assignments over the course of the semester. Late homework will not be accepted. Over the semester, I will give several quizzes that may relate to the reading, lecture material, or other topics I specify (e.g., Geologic Time Scale). Field Trip: If we can find a common time, we will take a three- to four-day trip to examine the Precambrian geology of Missouri. You are strongly encouraged to participate on this trip. Grade Scale: Grades will be determined based on the following criteria: Exams (3) 40% A % B % D % Final Exam 20% A % C % D 66-63% Labs 20% B % C 76-73% D % Homework, 20% B 86-83% C % 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. ADAAA Statement: DePauw University is committed to providing equal access to academic programs and university administered activities with reasonable accommodations to students with disabilities, in compliance with the Americans with Disabilities Act and Amendments (ADAAA). Any student who feels she or he may need an accommodation based on the impact of a disability or learning challenge is strongly encouraged to contact Pamela Roberts, Coordinator of Student Disability Services for further information on how to receive accommodations and support. Student Disability Services is located at 101 E. Seminary St.,
