3.
Research
proposal on topic in structural geology/tectonics using
GSA proposal guidelines.
Due
October 11. (8 %)
4.
Written
review (2000 word maximum) of a thesis (structure/tectonics
topic) in the
Geology Library. Due
November 1. (12 %)
5.
Revised version of research proposal.

6.
Class participation. (4
%)
Objectives:
1.
To think like a scientist instead of a student.
2.
To provide graduate students interested in structural
geology/tectonics with an adequate
background in continuum mechanics for more
advanced courses and research.
3.
To emphasize the fundamentals needed to write quality technical
reports and published papers.
