The oil and gas resource potential of the Arctic National Wildlife Refuge 1002 area, Alaska
In anticipation of the need for scientific support for policy decisions and in light of the decade-old perspective of a previous assessment, the USGS has completed a reassessment of the petroleum potential of the ANWR 1002 area. This was a comprehensive study by a team of USGS scientists in collaboration on technical issues (but not the assessment) with colleagues in other agencies and universitie

Examining risk in mineral exploration
Successful mineral exploration strategy requires identification of some of the risk sources and considering them in the decision-making process so that controllable risk can be reduced. Risk is defined as chance of failure or loss. Exploration is an economic activity involving risk and uncertainty, so risk also must be defined in an economic context. Risk reduction can be addressed in three fundam

An interpretation of the 1997 airborne electromagnetic (AEM) survey, Fort Huachuca vicinity, Cochise County, Arizona
In March of 1997, an airborne electromagnetic (AEM) survey of the Fort Huachuca Military Reservation and immediate surrounds was conducted. This survey was sponsored by the U.S. Army and contracted through the Geologic Division of the U.S. Geological Survey (USGS). Data were gathered by Geoterrex-Dighem Ltd. of Ottawa, Canada. The survey aircraft is surrounded by a coil through which a large curre

Physical, chemical, and isotopic data for samples from the Anderson Springs area, Lake County, California, 1998-1999
Anderson Springs is located about 90 miles (145 kilometers) north of San Francisco, California, in the southwestern part of Lake County. The area was first developed in the late 1800s as a health resort, which was active until the 1930s. In the rugged hills to the south of the resort were four small mercury mines of the eastern Mayacmas quicksilver district. About 1,260 flasks of mercury were prod

The Silent Canyon caldera complex — A three-dimensional model based on drill-hole stratigraphy and gravity inversion
The structural framework of Pahute Mesa, Nevada, is dominated by the Silent Canyon caldera complex, a buried, multiple collapse caldera complex. Using the boundary surface between low density Tertiary volcanogenic rocks and denser granitic and weakly metamorphosed sedimentary rocks (basement) as the outer fault surfaces for the modeled collapse caldera complex, it is postulated that the caldera co

Geologic datasets for weights-of-evidence analysis in Northeast Washington: 3. Minerals-related permits on national forests, 1967-1998
Permits to explore for and (or) develop mineral resources on forest land can be used to indicate
locations and types of mineral-related activities on national forests. Permits for these activities require
filing at the Forest Service a Notice of Intention (Notice) to conduct mineral exploration activities and (or)
a Plan of Operation (Plan). A Plan of Operation is required is significant activitie
