The Conterminous United States Mineral Assessment Project; background information to accompany folio of geologic, geochemical, geophysical, and mineral resources maps of the Reno 1 by 2 degree Quadrangle, Nevada and California

“…Starting perhaps at about 6 Mathe deformational style changed again, and the present-day structural pattern consisting of large basin-range blocks developed. This style of deformation continues to the present day (Bell, 1984;Bell and Katzer, 1990).…”

“…In addition to the county reports, previous regional geologic and mineral deposit studies in the Reno quadrangle include Russell (1885), Hill (1911), Vanderburg (1940), Bailey and Phoenix (1944), Schrader (1947), Lawrence (1963), Morrison (1964), Southern Pacific Company (1964, Silberman and others (1976), Hurley and others (1982), Bell (1984), Oldow (1984), Deino (1985), Sidder (1986Sidder ( , 1987, Quade and Tingley (1987), Stewart (1988), Stager and Tingley (1988), Cox and others (1991), Seedorff (1991), Schweickert and others (in press), and Doebrich and others ( 1991, in press). Regional geophysical studies include Thompson and Sandberg (1958), Thompson (1959), Erwin (1970), Stanley and others (1976), Nevada Bureau of Mines (1977), Erwin and Berg (1977), Schaefer (1983), Tabor and others (1983), Kucks and Hildenbrand (1987), Hildenbrand and Kucks (1988), and Blakely and Jachens (1991).…”

“…These studies include Byerly (1956), Slemmons (1956Slemmons ( , 1957, Thompson and others (1967), Thompson andBurke (1973, 1974), Anderson and others (1983), Okaya and Thompson (1985), Bell andKatzer (1987, 1990), and Schaefer (1988).…”

“…Both right-lateral and left-lateral faults are present in the Reno quadrangle. Strike-slip movement is thought to have occurred at various times throughout the late Cenozoic, and the youngest movement on these structures in the Reno quadrangle is historic (Bell, 1984).…”

Distinct mantle sources for Pliocene–Quaternary volcanism beneath the modern Sierra Nevada and adjacent Great Basin, northern California and western Nevada, USA

“…1). The volcanic centers lie on the Humboldt Lineament, an eastnortheast-to northeast-striking zone of faults, with relatively high seismicity, high heat fl ow, and geothermal activity that includes two producing geothermal plants (Faulds et al, 2005;Fultz et al, 1984;Rowan and Wetlaufer, 1981). The Humboldt Lineament appears to be a region of thin lithosphere (Louie et al, 2004) beneath which mantle-derived melts are able to make it to the surface.…”
