Geophysical Research and Development Completed
The Geophysical Research and Development Project supported the development of new and existing geophysical techniques for addressing critical geological problems. Research conducted under this project included development of needed geophysical methods and software, development of new geophysical instrumentation, and applications of geophysical techniques to frontier areas of geology.
Science Issue and Relevance
Many projects within the U.S. Geological Survey (USGS) use geophysics as a tool for studying buried or concealed geologic features. The availability of modern geophysical instrumentation and data interpretation software is often critical to the success of these projects. However, most projects using geophysics lack the resources to evaluate, purchase, maintain, and provide training for geophysical equipment and software. In addition, the development of any new geophysical technology is a risky, long-term activity, that is well beyond the scope of most individual projects.
Methods to Address Issue
The Geophysical Research and Development Project ran from 1996 to 2012 and provided the geophysical equipment and software tools USGS projects needed. The Project strived to anticipate and develop new geophysical technologies that the Survey would need within the next several years and supported the development of new and existing geophysical techniques to address critical geological problems.
Research conducted under this project includes development of needed geophysical methods and software, development of new geophysical instrumentation, and applications of geophysical techniques to frontier areas of geology.
Technologies supported and developed fell within the general categories of geoelectrical methods, potential-field methods, and gamma-ray methods. These methods permitted geophysical investigations at a broad range of scales from national and regional scales to local and site characterization scales, and at a range of depths from a few centimeters to tens of kilometers.
Supported geophysical methods include potential-field methods (gravity and magnetics), electrical methods (DC resistivity, induced polarization, and self-potential), electromagnetic methods (magnetotellurics (MT), ground penetrating radar (GPR), directional borehole radar, time-domain EM, and frequency-domain EM), shallow seismic methods (reflection, refraction, and surface-to-borehole), and gamma-ray geophysics.

Filter Total Items: 82Contributions to the gold metallogeny of northern Nevada
Nevada is one of the Earth's premier gold producing regions, accounting for approximately 64 percent of the U.S and nine percent of the world total. The impact of these mines on nearby local economies and on our national balance of payments is profound, and will continue well into the next century. Of principal importance in this region are giant sedimentary-rock-hosted (Carlin-type) deposits. TheElectrical resistivity survey in the Cornudas Mountains area, Otero County, New Mexico
No abstract available.AuthorsD. P. Klein, B. D. RodriguezDeep regional resistivity structure across the Carlin Trend
The genesis of gold deposits along the Carlin trend is not fully understood. Many of the significant mineral deposits in the Carlin trend were formed during the Tertiary as a result of interrelated high-angle basin-and-range faulting, intrusive igneous activity, and hydrothermal processes (Radtke, 1985). According to Shawe (1991), the linearity of the gold deposits along the Carlin trend and the sAuthorsBrian D. RodriguezPotential-field geophysical software for the PC, version 2.2
