Advanced Structural Geology
Geo 380C – Fall 2003

Instructor:	Randy Marrett	Geo 4.126, 471-2113, marrett@mail.utexas.edu

Hours:	lectures – MWF 2:00-3:00 in Geo 3.120	office hours – MWF 3:00-4:00 in Geo 4.126

Reading:	Ramsay and Huber, The Techniques of Modern Structural Geology
	Means, Stress and Strain 	* readings on web:  http://www.geo.utexas.edu/faculty/marrett/AdvStructure.htm
	and other books and articles on reserve in Geology Library

Topics:	Tensors and transformations;  stress ellipoids, tensors, and fields;  strain ellipsoids, tensors, and measurement;  rheology and deformation mechanisms

Grading:	1.	Eight problem sets handed out in class.  (8% each)	2.	Abstract of paper indicated in class.  Due September 3.  (8%)
	3.	Research proposal on topic in structural geology/tectonics using GSA 		proposal guidelines.  Due October 10.  (8 %)	4.	Written review (2000 word maximum) of a thesis (structure/tectonics topic)		in the Geology Library.  Due October 24.  (12 %)	5.	Revised version of research proposal.  Due November 5.  (4 %)	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.
