Structural Geology and Tectonics
Office: A462 Weeks Hall
I view myself as a quantitative field geologist. I try to use a simultaneous combination of field geology, geophysical methods, physical (analog) models, and numerical models to understand three-dimensional deformation. Ongoing projects are on a range of scales and crustal levels in order to consider deformation of the entire lithosphere. A list of ongoing projects, grouped thematically, is listed below.
Granite emplacement and magmatic arc processes
- California, Idaho, New Zealand, Minnesota
- San Andreas fault (USA), Jamaica, Honduras/El Salvador
- California, Tunisia
- California, Canada
- Norway, New Zealand, New Caledonia
In addition to field areas, we use several tools routinely
EBSD and universal stage analysis for LPO
Geomagnetism (Paleomagnetism and AMS)
Also, every year the structural geology group goes on a field trip, preferably to an exotic location. Here are some of the trips:
Norway - Combined Structural Geology / Petrology (2000)
Spain (Pyrenees) - Combined Structural Geology / Sedimentology (2001)
South Africa - Combined Structural Geology / Economic Geology (2002)
Utah (Dinosaur Nat'l Park) - Combined Structural Geology / Paleontology (2003)
California (San Andreas fault) - Combined Structural Geology / Geophysics (2004)
Argentina - Combined Structural Geology /Paleotology (2007)
Possible upcoming trips: Turkey, Cyprus, Newfoundland
