DC resistivity soundings were made to map subsurface lithologic, structural and hydrologic features important in controlling possible ground water contamination from mining activities and for design of remediation efforts.
Study to estimate the 3-D distribution of permafrost, to evaluate the effectiveness of these methods at mapping permafrost geometry, and to better define the physical properties of the subsurface in discontinuous permafrost areas.
A regional profile on the Utah-Nevada State line reveals a deeply penetrating, broad electrical conductor suggesting the southwestern limit of intact Archean crust is farther north than previously reported with implications for future mineral exploration.
Surveys originally carried out by Soviet geophysicists from 1972 through 1974 were digitized. Georeferencing was problematic as were some of the measured characteristics; we explain what we did and how we have understood these data.
