The use of uranium is an alternative energy source to petroleum products and some of the United States’ highest quality ore is located on the Colorado Plateau. However, some regions where suitable mining efforts are conducted include areas that are near important environmental resources such as National Parks that provide viewscapes and habitat for wildlife.
We operate a low–enriched uranium–fueled, pool–type reactor, the Geological Survey TRIGA® Reactor, to support science by providing information on geologic, plant, and animal specimens to advance methods and techniques unique to nuclear reactors. Samples from around the world are submitted to the USGS for analysis using the reactor facility.
The U.S. National Ice Core Laboratory is a facility for storing, curating, and studying ice cores recovered from the polar regions of the world. It provides scientists with the capability to conduct examinations and measurements on ice cores, and it preserves the integrity of these ice cores in a repository for current and future investigations.
The laboratory capabilities include imaging, x-ray analysis, x-ray mapping, image processing, and optical microscopy.
SHRIMP-RG stands for Sensitive High-Resolution Ion Microprobe with Reverse Geometry. We are committed to making SHRIMP-RG available to the scientific community and seek projects that require spatially resolved measurements and benefit from SHRIMP-RG's unique combination of high secondary transmission and high mass resolving power.
Computational fluid dynamics simulations of the Late Pleistocene Lake Bonneville flood
At approximately 18.0 ka, pluvial Lake Bonneville reached its maximum level. At its northeastern extent it was impounded by alluvium of the Marsh Creek Fan, which breached at some point north of Red Rock Pass (Idaho), leading to one of the largest floods on Earth. About 5320 km3 of water was discharged into the Snake River drainage and...Abril-Hernández, José M.; Periáñez, Raúl; O'Connor, Jim E.; Garcia-Castellanos, Daniel
James Dwight Dana and John Strong Newberry in the US Pacific Northwest: The roots of American fluvialism
Recognition of the power of rivers to carve landscapes transformed geology and geomorphology in the late nineteenth century. Wide acceptance of this concept—then known as “fluvialism”—owes to many factors and people, several associated with exploration of western North America. Especially famous are the federal geographic and geologic surveys of...O'Connor, Jim E.
Middle Pleistocene infill of Hinkley Valley by Mojave River sediment and associated lake sediment: Depositional architecture and deformation by strike-slip faults
Hinkley Valley in the Mojave Desert, near Barstow about 140 km northeast of Los Angeles and midway between Victorville Valley and the Lake Manix basin, contains a thick sedimentary sequence delivered by the Mojave River. Our study of sediment cores drilled in the valley indicates that Hinkley Valley was probably a closed playa basin with stream...Miller, David M.; Haddon, Elizabeth; Langenheim, Victoria; Cyr, Andrew J.; Wan, Elmira; Walkup, Laura; Starratt, Scott W.
Monogenetic origin of Ubehebe Crater maar volcano, Death Valley, California: Paleomagnetic and stratigraphic evidence
Paleomagnetic data for samples collected from outcrops of basaltic spatter at the Ubehebe Crater cluster, Death Valley National Park, California, record a single direction of remanent magnetization indicating that these materials were emplaced during a short duration, monogenetic eruption sequence ~ 2100 years ago. This...Champion, Duane E.; Cyr, Andrew J.; Fierstein, Judith; Hildreth, Edward
Stress concentrations at structural discontinuities in active fault zones in the western United States: Implications for permeability and fluid flow in geothermal fields
Slip can induce concentration of stresses at discontinuities along fault systems. These structural discontinuities, i.e., fault terminations, fault step-overs, intersections, bends, and other fault interaction areas, are known to host fluid flow in ore deposition systems, oil and gas reservoirs, and geothermal systems. We modeled stress transfer...Siler, Drew; Hinz, Nicholas H.; Faulds, James E.

Thermal influences on spontaneous rock dome exfoliation
Rock domes, with their onion-skin layers of exfoliation sheets, are among the most captivating landforms on Earth. Long recognized as integral in shaping domes, the exact mechanism(s) by which exfoliation occurs remains enigmatic, mainly due to the lack of direct observations of natural events. In August 2014, during the hottest days of summer, a...Collins, Brian D.; Stock, Greg M.; Eppes, Martha C.; Lewis, Scott W.; Corbett, Skye C.; Smith, Joel B.
The Colorado River and its deposits downstream from Grand Canyon in Arizona, California, and Nevada
Understanding the evolution of the Colorado River system has direct implications for (1) the processes and timing of continental-scale river system integration, (2) the formation of iconic landscapes like those in and around Grand Canyon, and (3) the availability of groundwater resources. Spatial patterns in the position and type of Colorado River...Crow, Ryan S.; Block, Debra L.; Felger, Tracey J.; House, P.

Punctuated sediment discharge during early Pliocene birth of the Colorado River: Evidence from regional stratigraphy, sedimentology, and paleontology
The Colorado River in the southwestern U.S. provides an excellent natural laboratory for studying the origins of a continent-scale river system, because deposits that formed prior to and during river initiation are well exposed in the lower river valley and nearby basinal sink. This paper presents a synthesis of regional stratigraphy,...Dorsey, Rebecca J.; O’Connell, Brennan; McDougall-Reid, Kristin; Homan, Mindy B.
Ore-forming adakitic porphyry produced by fractional crystallization of oxidized basaltic magmas in a subcrustal chamber (Jiamate, East Junggar, NW China)
Adakitic intrusions are supposed to have a close genetic and spatial relationship to porphyry Cu deposits. However, the genesis of adakitic intrusions is still under dispute. Here, we describe newly discovered intrusive complex rocks, which are composed of ore-bearing, layered magnetite-bearing gabbroic and adakitic rocks in Jiamate, East Junggar...Hong, Tao; Xu, Xing-Wang; Gao, Jun; Peters, Stephen; Zhang, Di; Jielili, Reyaniguli; Xiang, Peng; Li, Hao; Wu, Chu; You, Jun; Liu, Jie; Ke, Qiang
Networking our science to characterize the state, vulnerabilities, and management opportunities of soil organic matter
Soil organic matter (SOM) supports the Earth's ability to sustain terrestrial ecosystems, provide food and fiber, and retains the largest pool of actively cycling carbon. Over 75% of the soil organic carbon (SOC) in the top meter of soil is directly affected by human land use. Large land areas have lost SOC as a result of land use practices, yet...Harden, Jennifer W.; Hugelius, Gustaf; Ahlström, Anders; Blankinship, Joseph C.; Bond-Lamberty, Ben; Lawrence, Corey; Loisel, Julie; Malhotra, Avni; Jackson, Robert B.; Ogle, Stephen M.; Phillips, Claire; Ryals, Rebecca; Todd-Brown, Katherine; Vargas, Rodrigo; Vergara, Sintana E.; Cotrufo, M.

Element migration of pyrites during ductile deformation of the Yuleken porphyry Cu deposit (NW-China)
The strongly deformed Yuleken porphyry Cu deposit (YPCD) occurs in the Kalaxiangar porphyry Cu belt (KPCB), which occupies the central area of the Central Asian Orogenic Belt (CAOB) between the Sawu’er island arc and the Altay Terrane in northern Xinjiang. The YPCD is one of several typical subduction-related deposits in the KPCB, which has...Hong, Tao; Xu, Xing-Wang; Gao, Jun; Peters, Stephen; Li, Jilei; Cao, Mingjian; Xiang, Peng; Wu, Chu; You, Jun
The natural oil seep in this photo is located in Pescadero Creek County Park, where the Canyon Trail crosses Tarwater Creek. The oil is black, has a taffy-like consistency, and smells like motor oil.
The Half Moon Bay oil field is one of the oldest oil fields in California and was first developed during the 1880s. Since then, the field has produced an estimated 60,000 barrels of oil from about 19 wells. Most of the old wells have been plugged and abandoned, but this well was reworked in 1980 and produces small volumes of oil from thin sandstone layers of the Miocene...
