Timber Mountain–Oasis Valley caldera complex of southern Nevada

K-Ar ages and paleomagnetic directions from the Lathrop Wells Volcanic Center, southwestern Nevada; an evaluation of polycyclic volcanism

“…Locally, the Nevada Test Site area consists of a number of coalesced caldera complexes that were active during the Miocene (14 to 8 Ma) (Byers et aL, 1976;Christiansen et al, 1977). Since then volcanism has continued in the form of small isolated subalkaline (hypersthene normative) to alkaline undersaturated (nepheline normative) basaltic volcanic fields (Vaniman and Crowe, 1981;Vaniman et al, 1982).…”

Contaminant Transport Parameters for the Groundwater Flow and Contaminant Transport Model of Corrective Action Units 101 and 102: Central and Western Pahute Mesa, Nye County, Nevada, Revision 0

“…North-to-south trending basin and range faults have disrupted the volcanic plateau and formed linear mountain ranges separated by sediment-filled troughs. Yucca Mountain is an east-tilted fault block consisting of a thick sequence of tuffs erupted from the middle to late Miocene Timber Mountain-Oasis Valley caldera complex located to the north and west (Broxton et al, 1987;Byers et al, 1976;Christiansen et al, 1977). …”

“…To this end, flow and transport models are being developed over a range of scales for the UGTA CAUs. For the Central and Western Pahute Mesa CAUs, the predominant hydrologic flow pathways from the test cavities are through locally hydrologically conductive Cenozoic volcanic rocks that were erupted and deposited during multiple eruptive cycles of the Timber Mountain and Silent Canyon caldera complexes (Christiansen et al, 1977;Byers et al, 1976;Broxton et al, 1989;Byers et al, 1989;Sawyer et al, 1994). Probability distributions for flow and transport parameters for these rocks are required input for the models.…”

Geologic and hydrologic investigations of a potential nuclear waste disposal site at Yucca Mountain, southern Nevada

“…4.1) (Christiansen andothers, 1965, 1977;Byers and others, 1976b), which consists of locally thick and, in some areas, highly faulted sequences of Tertiary silicic volcanic rocks, mainly lavas and ash-flow tuffs about 8-15 m.y. old, roughly centered around the Timber Mountain and Silent Canyon (Noble and others, 1968) (Carr, 1984a, b), a northwest-southeast-trending zone of diverse structure and topography, 75 to 125 km mi) wide, lying between the tectonically more active InyoMono (Carr, 1984a, b) and Basin-Range subsections ( fig.…”
