TEXT:
An Introduction to Igneous and Metamorphic Petrology, John D. Winter,
Prentice Hall, 2001.

Text will be supplemented with handouts and by readings from books
on reserve.
Objectives of the Course
Course Outline
Evaluation
In this course you will acquire tools to systematically approach a range
of geologic
questions that the rock record can help answer. By the end of
the course you should be able to:
Identify igneous and metamorphic rocks in hand sample.
Examine thin sections of a rock to describe its texture and identify
minerals present.
Interpret the texture and mineral content in terms of the petrogenetic
processes that may have produced the rock.
Interpret phase diagrams to explain how equilibrium mineral assemblages
change under different conditions in various locations on earth.
Use phase diagrams as an aid in hypothesizing how a particular rock
may have formed.
Use knowledge of stable mineral assemblages as an aid in rock and mineral
identification.
Draw a detailed “rock cycle” concept map showing processes and products
involved in the differentiation of the solid earth over time.
Describe the connection between plate tectonics and occurrence of rock
types.
Explain how rocks can serve as records of geologic processes.

Exam Dates: Exam 1 on Wednesday Feb. 11, Exam 2 on Wednesday March
31
and the Final Exam on Tuesday May 4 from 6:00 to 7:50 p.m. (note unusual
date and time)
Grades will be based on assignments, exams, field trip reports (virtual
and real), and a group project.
| All course requirements must be completed to pass the course: | Percentage of grade |
| Assignments | 10% |
| Exams (three) | 30% |
| Field Trip Reports | 30% |
| Group Project | 30% |
The grading scale is as follows:
A 100-90%; B 89-80%; C 79-70%; D 69-60%; F 59% and lower.
Incompletes will be given only in accordance with University policies as published in the catalog.
Course Policies
Policy on attendance: Because there are so many in-class activities in this course, regular class attendance is expected.
Policy on missed exams: If you miss an exam, you may NOT make up that exam at a later date. You may, however, take a comprehensive exam on April 22 and use this in place of the missed exam. I give three exams in this course, and I typically drop the lowest score. However, you must take all of the exams! (Don’t even think about skipping the final!)
Policy on late assignments: Late assignments will not be accepted.
Other Important Dates:
-Drop date is March 19
_Student Research and Creative Activities Symposium is April 16
