University of South Dakota Lecture Meetings: MWF 2:00-2:50 in
Akeley-208 |
Course Overview: Petrology is the study of rocks. This course covers igneous and metamorphic rocks. These rocks are commonly covered together because they can both be considered as the result of the chemical process of crystallization, either directly from a magma in the case of igneous rocks, or recrystallization of another rock in metamorphic rocks. The occurrence, texture, mineralogy, and chemistry of these rocks reflects the processes that formed them at many scales, from the microscopic to the tectonic. By the end of the course students will:
Course Structure: Class meetings will consist of lectures and in-class problem solving sessions. Labs will generally involve examination of rocks in both hand sample and thin section, with questions designed to focus students on interpretation of the rocks. There will be "out of class" lab quizzes like mineralogy. There will be two midterm and a final covering lecture material. There will be a required late-semester field trip.
Field Trip: We will take a weekend (Friday-Sunday) field trip late in the semester; the destination will be either the Black Hills or Minnesota, tentatively scheduled for April 25-27.
Other Materials: 10x hand lens (preferably a triplet)
Grading: A single grade is assigned integrating lecture and laboratory performance. Grading will be on a curve, but set no more stringently then the standard 90/80/70/60 scale. The weighting of course work will be as follows:
| Labs/Assignments | 20% |
| Lab Quizzes | 20% |
| Midterm Exams | 30% |
| Final Exam | 25% |
| The Floating Five* | 5% |
*5% added to weight of best exam
Office Hours: M 10-11, Tu 10-12, Th 1-3; also, feel free to swing by any time or make an appointment
Cheating: Don’t do it! The
university policy on cheating is as follows: “No credit can be given for a
dishonest assignment. At the discretion of the instructor, a student caught
engaging in any form of academic dishonesty may be: (a) given a zero for that
assignment; (b) allowed to rewrite and resubmit the assignment for credit; (c)
assigned a reduced grade for the course; (d) dropped from the course; or (e)
failed in the course.”
Freedom in Learning: Students are responsible for
learning the content of any course of study in which they are enrolled. Under
Board of Regents and University policy, student academic performance shall be
evaluated solely on an academic basis and students should be free to take
reasoned exception to the data or views offered in any course of study. Students
who believe that an academic evaluation is unrelated to academic standards but
is related instead to judgment of their personal opinion or conduct should first
contact the instructor of the course. If the student remains unsatisfied, the
student may contact the department head and/or dean of the college which offers
the class to initiate a review of the evaluation.
Disabilities: Any student who feels s/he may need
academic accommodations or access accommodations based on the impact of a
documented disability should contact and register with Disability Services
during the first week of class. Disability Services is the official office to
assist students through the process of disability verification and coordination
of appropriate and reasonable accommodations. Students currently registered with
Disability Services must obtain a new accommodation memo each semester.
Course Evaluation: You will have an opportunity to
evaluate the course and the instructor using the IDEA Diagnostic Form at the end
of the semester.
