Cenozoic transverse zones and igneous belts in the Great Basin, Western United States: Their tectonic and economic implications

Gravity Data from Dry Lake and Delamar Valleys, east-central Nevada

“…The western margin of Delamar Valley is displaced considerably westward of the same margin of Dry Lake Valley. The displacement appears to have been accommodated along an E-W line of maxspots perhaps representing one of the enigmatic transverse zones (Rowley, 1998;Rowley and Dixon, 2001) sometimes noted in the Great Basin. These transverse zones typically are reflected by east-striking faults and folds, alignments of plutons and volcanic vents, and various alignments of local features (for example, springs, altered rock, mineral deposits).…”

“…These transverse zones typically are reflected by east-striking faults and folds, alignments of plutons and volcanic vents, and various alignments of local features (for example, springs, altered rock, mineral deposits). A belt of faulted rocks with low relief occurs in the area between Dry Lake and Delamar Valleys and is termed the "Timpahute transverse zone" (Rowley, 1998;Dixon and others, 2007).…”

Inversion of Gravity Data to Define the Pre-Cenozoic Surface and Regional Structures Possibly Influencing Groundwater Flow in the Rainier Mesa Region, Nye County, Nevada.

“…The interpreted ridge striking SSW from Kawich Valley to Rainier Mesa (and possibly beyond) may represent a major barrier and/or conduit (e.g., Rowley, 1998;Mankinen and others, 2003) …”

Hydrology and simulation of ground-water flow in Cedar Valley, Iron County, Utah

“…Structural geologic studies of the area were completed by Averitt (1962), Threet (1963), and Stewart and others (1972a, b). Most recent geologic studies examined the Cedar Valley area as a part of regionalscale studies on the transition between the Basin and Range and Colorado Plateau (Maldonado, 1995;Maldonado and others, 1997;Williams and Maldonado, 1995;and Rowley, 1998). A summary of previous geologic studies and new interpretations of basin-fill stratigraphy are presented in Hurlow (2002).…”
