Inventory of granitic masses in the State of Nevada

Evidence for a Battle Mountain‐Eureka crustal fault zone, north‐central Nevada, and its relation to Neoproterozoic‐Early Paleozoic continental breakup

“…The upper sedimentary/igneous basement refers to the sedimentary rocks that were deposited on the crystalline basement during Precambrian and Paleozoic time and deformed during subsequent tectonic events, and all igneous rocks that subsequently intruded them. Independent information was used to constrain the elements of the models 1 , including geology [ Stewart and Carlson , 1976a, 1977; Stewart et al , 1977; Spengler et al , 1979; Stewart , 1980; Poole et al , 1992], MT models [ Wannamaker et al , 1997; Rodriguez and Williams , 2001, 2002], gravity models and interpretations [ Thompson et al , 1989; Blakely and Jachens , 1991; Catchings and Mooney , 1991; Zoback et al , 1994; Saltus and Jachens , 1995; Kaban and Mooney , 2001], density measurements [ Mabey , 1965; Telford et al , 1976], seismic reflection and refraction models [ Potter et al , 1987; Catchings and Mooney , 1991; Holbrook et al , 1991], and magnetic interpretations [ Blakely , 1988; Zoback et al , 1994; Grauch , 1996]. …”

“…Eastern assemblage, or miogeoclinal rocks, in the eastern area of the geophysical models, consist of thick sections of dolomite intermixed with clastic rocks [ Stewart , 1980; Poole et al , 1992], which likely average about 2680 kg/m 3 [ Mabey , 1965]. Density differences between west and east have been attributed to variations in igneous rock composition as well [ Blakely and Jachens , 1991], with more silicic igneous rocks inferred southwest of the BME trend, and more intermediate‐composition rocks on the northeast [ Stewart and Carlson , 1976b; Spengler et al , 1979; Zoback et al , 1994; John et al , 2000] (Figure 6). During periods of extension, the intruding magmas may have been guided by a preexisting density difference in the sedimentary section [ Glazner and Ussler , 1989].…”

U.S. Geological Survey research in radioactive waste disposal - Fiscal year 1979

“…Southern Nevada (off the NTS): A search for potential repository sites in granite (Spengler, Maldonado, Weir, and Dixon, 1979), shale/argillite (Simpson and others, 1979), and tuff was conducted in southern Nevada, on the basis of information in existing reports and limited field reconnaissance. The Nevada Bureau of Mines and Geology is participating in this work through a contract to perform mineral assessments on potential sites identified from the geologic reconnaissance.…”
