Doug Walker -Doug's interests include the use of stratified rocks
to understand structural and tectonic development of extensional orogens. He has used
techniques of sedimentation and tectonics to better understand the timing of deformation
and the nature of crustal responses in extensional orogens. Current research projects
are described below. The East Sierran thrust belt is a zone of ductile thrusts and
folds that developed along the eastern edge of the Sierran arc of California in Jurassic
time. Work involves basic field mapping along with structural analysis, GIS databases,
and U-Pb geochronology. Other work concentrates on the relation of magmatism to
crustal extension. This work focuses on magma sources and depth of melting in extensional
systems. A new effort will attempt to created a comprehensive database for western North
America magmatism and develop tools for spatial and thematic query (all web accessible).
Another research direction involves the transition from extension to transcurrent faulting
in the southwestern Basin and Range of California. This work is on how deformation has
progressed over the last 5 million years in the Death Valley/Owens Valley areas. During
this time there was a significant change from mostly extension to transcurrent deformation.
Doug's work is to try to quantify these changes using field geology, GIS, GPS, tectonic
geomorphology, basin analysis, and other techniques.
Beth McLellan - Beth's research concentrates on U/Pb dating of detrital zircons
and metamorphic petrology. Her current research concentrates on reconstructions of tectonic
history and terrane accretion in Norway and North America.
Diane Kamola - Diane is working on a number of studies involving tectonics and
sedimentary processes. One area of research is the relation between stratal stacking
patterns and thrust sheet development in foreland basin settings, which looks at the
interaction between geological processes active in the foreland basin. A second area is
the tectonostratigraphy of extensional basins in the Basin and Range, aimed at
understanding the spatial relation and temporal variation of paleostructure and
paleogeographic development. This research also provides insights on paleogeographic
and structural development on the regional scale.
Bob Goldstein - Bob has been a pioneer in employing fluid inclusion technologies in
sedimentary rocks. These techniques are useful for evaluating temperature and pressure of
deformation, and for determining thermal histories of sedimentary basins. In particular,
Bob is now working on relating fluid flow and thermal history in foreland basins to tectonic
history. He has also been doing more work recently on rift basins that have been inverted
during compressional events. It appears that these settings are overprinted by hydrothermal
injection of hot fluids after the major inversion events, charging petroleum reservoirs
with hot fluids responsible for thermal maturation, injecting hydrocarbons, and causing
dissolution of carbonates and precipitation of quartz overgrowths in sandstone petroleum
reservoirs.
Randy Van Schmus - Prof. Van Schmus works primarily with Precambrian orogenic
terranes and with geochronology of igneous rocks associated with them. However, most
terranes being studied also include major components of siliciclastic metasedimentary
rocks, and Van Schmus' recent studies have included constraining depositional ages,
provenance, and histories of basin formation using U-Pb ages of detrital zircon populations
in order to understand better the tectonic evolution of terranes containing the metasedimentary
rocks.
Daniel Stockli Dan's research focuses primarily on the integrated application of
thermochronology and geochronology to tectonic problems. He combines structural geology
with (U-Th)/He, fission track and 40 Ar/39Ar low-temperature thermochronology to elucidate
the spatial and temporal distribution of deformation in continental rifting, orogen-parallel
extension and lateral extrusion tectonics, and the timing and strain distribution of
intraplate deformation and strain partitioning in extensional and contractile fault
systems. For the past six years he has studied the spatial and temporal distribution
and magnitude of extensional and strike-slip faulting in the northern Basin and Range
province, the northern Gulf of California, and Sonora. A more recent focus is the tectonics
of the Middle East, especially the continent-continent collision in northern and southern
Iran, and the timing and structural configuration of initial rifting along the margins
of the Red Sea in Egypt and Saudi Arabia. A new project is trying to investigate the
timing of east-west extension and crustal extrusion in southern Tibet. The Neogene
geodynamics of the Tibetan-Himalayan orogenic belt, and the Tibetan Plateau in particular,
is central to the understanding of how plateaus form and collapse and how continental
crust deforms.
