My research examines the
tectonic evolution of continental margins
by combining detailed geologic mapping of
sedimentary and volcanic rocks and faults
with a variety of laboratory techniques,
including geochronology, geochemistry,
petrography and paleomagnetics.
This research is on a spectrum of topics,
including volcanology, sedimentology,
structural geology, petroleum geology,
economic geology, geochemistry, and
geothermal exploration.
My major project for the past decade focuses on the Cenozoic trantensional rifting along the Sierra Nevada range front and western Walker Lane belt in California and Nevada. A second active project focuses on the stratigraphic and structural setting of the largest Cenozoic silicic igneous province and epithermal mineral province on Earth: the Sierra Madre Occidental in Mexico. The most continuous strand of my research (since 1978) investigates the growth of continents at extensional arcs, in both continental and oceanic settings. Although most of my research funding has come from NSF, I have become increasingly attracted to work in geothermal exploration.
