Abstract
The right-divergent Fish Lake Valley fault zone (FL VFZ), a 80 KM-long component of the northern Death Valley fault system, comprises contemporaneous NW-striking dextral faults, N-striking normal faults, NE-striking left(?)-divergent faults, and locally WNW-striking contractional faults. The fault zone terminate s in a horsetail splay where the minimum right-slip rate is 0 .7--0.8 mm/yr. The styles and rates of faulting are based on a sequence of morphostratigraphic units disrupted by the FL VFZ. Geomorphic surface correlation s, radiocarbon analyses, tephrochronology, and soil development studies were used to estimate unit ages. Paleoseismicity studies have identified three discrete slip events in the last 4 to 2 ka on the northern FL VFZ. The last two significant events were similar, suggesting a characteristic earthquake behavior and magnitude s of 7. 1 ± 0.3. The last large event occurred 1 ka (±0 .6, -0.5) and comparable events have repeated every 1. 1 Ka ( +2 . 3, -0.5 ). Source structure characteristics suggest a MCE of M 7.3 ± 0.4.

Faulting and tectonics in the foreland basin fold/thrust belt of the San Juan Province, Argentina, and a comparison to the Yakima fold/thrust belt of the northwestern United States
Whitney, Robert A (University of Nevada, Reno, 1991)The San Juan Province of west-central Argentina lies in a region of crustal shortening, the result of subhorizontal subduction in the Peru-Chile trench to the west. This crustal shortening is manifest as a north-south ... -

Structural-tectonic analysis of northern Dixie Valley, Nevada
Whitney, Robert A (University of Nevada, Reno, 1980)Structural-tectonic and surficial geologic studies of northern Dixie Valley, Nevada, using photogeologic methods, indicate the valley is a complex asymmetric graben bounded by high-angle Basin and Range faults. The graben ... -

The engineering properties of alluvial/colluvial fault scarp soils in the western Basin and Range, and their influence on fault scarp morphology/dating
Prokop, Christopher J. (University of Nevada, Reno, 1983)Both field and laboratory studies of the alluvial/colluvial soils, derived from various lithologies, that comprise the 1954 Dixie Valley – Fairview Peak fault scarps and the 1915 Pleasant Valley fault scarps of west- central ...
