Stratigraphy, Structure, and Fluid Flow at the Soda Lake Geothermal Field, western Nevada, USA
… southern part of the Carson Sink basin of northwestern Nevada within the Basin and Range of the western USA. The Basin and Range is a world-class geothermal province with significant untapped potential, particularly in blind (no surface hot springs or steam vents) geothermal systems. Blind …

INFERRED RHEOLOGY AND UPPER MANTLE CONDITIONS OF WESTERN NEVADA AND SOUTHERN CALIFORNIA-NORTHWEST MEXICO
Understanding the viscous strength (rheology) of the mantle is essential for understanding the dynamics and evolution of the Earth. Rheology affects many geologic processes such as mantle convection, the earthquake cycle, and plate tectonics. This study uses tectonic (postseismic) and non-tectonic …

A Stone's Throw from the Source: An Examination of Fine-Grained Volcanic Toolstone Use in the Pah Rah Range, Western Nevada
Prehistoric use of the Pah Rah Range in western Nevada has resulted in a diverse record of hunting, processing, and residential sites, many of which contain artifacts manufactured from fine-grained volcanic (FGV) toolstones. Using data from the X-ray fluorescence analysis of 303 FGV artifacts from …

Paleoindian technological provisioning in the western Great Basin
… assemblages from two stemmed point sites in western Nevada, the Sadmat and Coleman sites. These sites are located in the Lahontan basin and possess data sets unique and compelling in addressing the research objectives proposed in this study; Further, this thesis examines the technological …

The Relationship Between Paleoindian Site Location and Terminal Pleistocene/Early Holocene Lake-Level Fluctuations in the Lahontan basin, Nevada
… for lacustrine settings. The Lahontan basin of western Nevada contains a rich record of Terminal Pleistocene and Early Holocene (TP/EH) (~16,000 - 8300 cal BP) lake-level fluctuations and Paleoindian occupation. In 2008, Ken Adams and colleagues compared the relationship between site location …

Analysis of Paleoindian Site Structure and Toolstone Procurement at the Overlook Site (26CH3413), Churchill County, Nevada
… Paleoindian site located in Churchill County, western Nevada the Overlook Site (26CH3413) represents the remains of a residential base camp; a place from which local toolstone was procured to replace broken and expended tools fashioned on non-local material. To test this hypothesis several …

Spatial and Temporal Characterization of the Petrified Springs Fault, Central Walker Lane, Nevada: Documenting Middle Miocene Dextral Slip
… an active dextral shear zone superimposed on the western boundary of the Basin and Range extensional province. Approximately 25% of dextral shear along the Pacific-North American plate boundary accommodated in the Walker Lane, a NW-striking, intracontinental dextral fault system in eastern …

Examining the Impact of Mercury on Waterfowl with Implications for Human Health and Water Management in Arid Environments
… ducks along the lower Carson River watershed in western Nevada. Mercury (Hg) contamination of the Carson River dates back to the Comstock era mines in the late 1800's, where Hg amalgamation methods were used to extract silver and gold from ore deposits. Wood ducks frequently use this river …

Seed Dispersal of Wild Peony (Paeonia brownii): as seed in the pouch is worth two in the pod
… between 1550-1580 m in the mountain ranges of western Nevada. Wild peony appears to follow a scatter-caching seed dispersal syndrome, but this has never been explored. Scatter-caching is an unexpected dispersal mechanism for peony, considering that most rodent dispersed plants are large, woody …

Understanding late Cenozoic western United States mantle dynamics and surface tectonics using forward-adjoint data assimilation models
… the reconstruction of mantle dynamics below the western United States (U.S.) since 20 million years ago (Ma). In our model, the mantle dynamics is only driven by the mantle density structure. The model results reveal a new explanation for the formation of intra-plate volcanism in the western U.S. …

Hydrochemical Response of Groundwater Following the 2020 Monte Cristo Range Earthquake Sequence within Mineral and Esmeralda Counties, NV
The 2020 Monte Cristo Earthquake sequence in western Nevada began with a M 6.5 shock on 5/15/2020, and was the largest to occur in Nevada since 1954. The event exhibited left-lateral slip along an eastward extension of the Candelaria fault and extensive distributed surface faulting in the …

Mineral Ridge: A Late Cretaceous Orogenic Gold System in the Miocene Silver Peak-Lone Mountain Metamorphic Core Complex
… Peak metamorphic core complex in west-central Nevada are contained in highly deformed, sheeted milky quartz veins that cut Neoproterozoic metasedimentary rocks and Cretaceous peraluminous granite and migmatite. Gold production at Mineral Ridge since discovery in 1864 has been approximately 1 …

Depositional constraints on lacustrine carbonates from the Winnemucca Dry Lake Basin, Nevada, USA
… located in the Basin and Range Province of western Nevada (USA). Tufas are in-situ accretionary carbonate deposits that build upward from the lake floor, and the largest of these structures rises more than 100 m above base level in the Pyramid Lake basin. Tufas were deposited mainly during …
