Chemical composition of sediments and soils are of interest because of the potential for human and wildlife health impacts from high metal contents due to over 100 years of mining activity.
Detailed chemical and isotopic analysis of host and associated rocks within an area that is currently the largest producer of gold in the US. Part of a study of the hydrothermal activity leading to the formation of these gold deposits.
In this area of historical lead-zinc mining activity, studies such as this help to assess the possibility of human exposure to cadmium and lead through eating fish.
Density and magnetic susceptibility measurements to assist in interpretation of gravity and magnetic anomaly data
Results from sediment cores collected during 1997-1999 oxbow lakes and beaver ponds to assess impact of historic mining and exposed mineral deposits on the quality of the water and the aquatic and riparian habitats.
Geochemical and mineralogical analysis of uranium-bearing sandstone in order to help understand mineral deposits of this type.
Geochemical and radionuclide analyses of surface samples and cores taken near the outflow of this old uranium mine.
Mineralogical data on samples from the surface and from drill cores, with geological observations help to understand the hydrology and effects of geology on acid-rock drainage in a mineralized alpine watershed.
Data from more than 660 gravity stations, 100 line-km of truck-towed magnetometer traverses, and 260 physical-property sites in this area.
Results of magnetic susceptibility (MS) measurements and magnetic mineralogy of sediments sampled in three cores from the south basin of Great Salt Lake
Mathematical modeling, coupled with new observations of magnetic susceptibility, yield better estimates of the underground configuration of granite plutons.
One hundred years of historical mining has resulted in substantial ongoing input of cadmium, lead, and zinc into the environment. This surficial-soil sampling and coring study provides information needed to support remediation efforts.
