Geologic Map of the Hiller Mountains Quadrangle, Clark County, Nevada and Mohave County, Arizona, NBMG M137

Resource Abstract:

1:24,000 scale Geologic Map of the Hiller Mountains Quadrangle, Clark County, Nevada, NBMG M137. Detailed geologic mapping by Keith A. Howard (USGS), Simon J. Hook (NASA), Geoffrey A. Phelps (USGS), and Debra L. Block (USGS). Nevada Bureau of Mines Map 137. The Hiller Mountains Quadrangle lies within the Lake Mead National Recreation Area. The quadrangle was mapped as part of a team effort studying the Lake Mead 30' x 60 Quadrangle. This is a full-color geologic map of the Heller Mountains Quadrangle that straddles Virgin Canyon in the eastern part of Lake Mead. Proterozoic gneisses and granitoid rocks underlie much of the quadrangle. They are overlain by upper Miocene basin-filling deposits of arkosic conglomerate, basalt, and the overlying Hualapai Limestone. Inception of the Colorado River followed deposition of the Hualapai Limestone and caused incision of the older rocks. Fluvial gravel deposits indicate various courses of the early river across passes through highlands of the Gold Butte-Hiller Mountain-White Hills structural block. Faults and tilted rocks in the quadrangle record tectonic extension that climaxed in middle Miocene time. Geologic mapping was supported by the National Cooperative Geologic Mapping Program of the U.S. Geological Survey, in cooperation with the National Aeronautics and Space Administration (NASA) and the National Park Service. The Nevada part of the quadrangle was previously mapped in reconnaissance by Volborth (1962) and Longwell and others (1965). Field work and map interpretation benefited from NASA airborne surveys in 1997 and 1998 using the Thermal Infrared Multispectral Scanner (TIMS) and MODIS/ASTER Airborne Simulator (MASTER) (Hook and others, 2001a). Base from U.S. Geological Survey, Hiller Mountains, 1983. The GIS work was in support of the U. S. Geological Survey COGEOMAP program.
