Petrography of Igneous and Metamorphic Rocks, 2003, Philpotts, A., Waveland Press Inc., ISBN 1577662954, 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 100-93% B- 82-80% D+ 69-67% Final Exam 20% A- 92-90% C+ 79-77% D 66-63% Labs 20% B+ 89-87% C 76-73% D- 62-60% Homework, 20% 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.
