Geoscientists from the University of Nevada will present research at two Geological Society of America meetings to be held in Washington and Utah. They will present at the Cordilleran Section meeting on May 4-6 at the University of Western Washington in Bellingham, Wash. and at the Rocky Mountain section meeting on May 7-9 at the Dixie Center in St. George, Utah.
- Daniel Sturmer, graduate teaching assistant in geological sciences: Kinematic Evolution of the Olinghouse Fault in the Northern Walker Lane, Western Nevada: A Left-Bilateral Fault Zone in a Region of Dextral Shear. Co-authors include James Faulds, research geologist with the Nevada Bureau of Mines and Geology. The fault zone accommodates for 15-25 percent of the Pacific-North America plate motion and will be examined to better understand other developing continental fault boundaries.
- Robert Watters, professor of geological sciences: Influence of Geological Structure and Alteration Strength on Edifice Failure Mode at Mt. Baker, Washington. Co-author: Sean Warren, graduate research assistant in geological sciences. An analysis of future failure geometries at Mount Baker from data and rock samples obtained from the Sherman Crater in August 2006 that were combined with laboratory testing and computer modeling.
- Benjamin M. Delwiche, graduate teaching assistant in geological sciences: Late Oligocene Paleotopography and Structural Evolution of the Pah Rah Range, Western Nevada: Implications for Constraining Slip on the Right-Lateral Warm Springs Valley Fault in the Northern Walker Lane. Co-authors: James Faulds and Christopher Henry, research geologists with the Nevada Bureau of Mines and Geology. The Evolution of transform faulting and propagation of extension and volcanism in the west-northwest margin of the Basin and Range Province, USA.
- James Faulds, research geologist with the Nevada Bureau of Mines and Geology: Evidence for Dextral Shear Along the Western Margin of the Carson Sink: The Missing Link Between the Central and Northern Walker Lane, Western Nevada. Between the Walker Lake and Pyramid lake domains is the Carson domain and large composite basin of the Carson Sink. Major dextral faults have not been documented in the Carson domain.
- Winifred Kortemeier, geological sciences: A Pliocene-Pleistocene Basaltic Phreatomagmatic Vent on the West Shore of Lake Tahoe, California: Implications for Early Tahoe Basin. Co-author: Richard Schweickert, professor of geological sciences. Basaltic rocks in the northwest part of the Tahoe basin locally interacted with lake waters provide insights into the processes that created Lake Tahoe.
- Danielle Villa, graduate teaching assistant in biological sciences: Late Paleozoic Deformation at Edna Mountain, Humboldt County, Nevada. Co-authors include: Patricia Cashman, research associate professor in geological sciences, and James Trexler, professor of geological sciences. Folding, faulting and regionally significant unconformities provide evidence for four previously undocumented late Paleozoic deformational events in the Edna Mountain area.
- Larry Garside, economic geologist with the Nevada Bureau of Mines and Geology: Nevada Geothermal Resources - 2007 Update. Co-author: Lisa Shevenell, research hydrogeologist with the Nevada Bureau of Mines and Geology. The potential for high, low and moderate temperature geothermal resources in Nevada.
- Garrett Vice, graduate research assistant with the Nevada Bureau of Mines and Geology: Characterizing the structural controls of the terraced Hill-Astor Pass geothermal systems in northwestern Nevada. Co-authors: James Faulds, research geologist with the Nevada Bureau of Mines and Geology, and Mark Coolbaugh, research assistant professor with the Great Basin Center for Geothermal Energy. Vice will explain the interaction between faults and geothermal systems that can facilitate the identification and production of hidden or blind geothermal reservoirs.
- Jill Pocock, graduate research assistant in geological sciences:Lithologic Mapping of the Terraced Hills, Northwestern Pyramid Lake, Nevada, Using Aster and HyMap Remote Sensing Data. Co-authors include: with graduate research assistants Shane Thompson, Zan Aslett, Laura Huebner, and Garrett Vice. The research compares two different remote sensing data sets that identify and map unique mineralogical end-members. It is part of an ongoing geologic and geothermal study focused on alteration within the Terraced Hills in the northwestern Basin and Range.
