This report presents the results of over 1100 geochemical analyses of samples of soil and sediment from the Coeur d'Alène (CdA) drainage basin in northern Idaho. The location (in 3 dimensions) and a lithological description of each sample is included wit
Sediment magnetic and geochemical results have been obtained from the top 60 meters of lacustrine sediments recovered in two cores from Tule Lake in northern California. The sediment magnetic and geochemical data, presented here in tabular form, compleme
This report presents geochemical analyses for 210 unaltered and unmineralized rock samples of Paleozoic age in the western Brooks Range of northern Alaska. These data form the basis for a study by Slack et al. (2004a) on the provenance and depositional hi
This report presents geochemical analyses for 220 mostly altered and mineralized rock samples from the Red Dog Zn-Pb-Ag district in the western Brooks Range of northern Alaska. These data form the basis for a study by Slack et al. (2004a) on hydrothermal
In the early 20th century, approximately 6 million metric tons of copper ore were mined from numerous deposits located along the shorelines of fjords and islands in Prince William Sound, Alaska. At the Beatson, Ellamar, and Threeman mine sites (fig. 1), r
Regional-scale geochemical survey designed to serve as a baseline for further analyses, and to understand effects of historical mining in the area.
Geochemical data from 2560 stream sediment samples collected in Puerto Rico, 421 soil samples collected on Isla de Vieques, and 35 soil samples were collected on Isla de Culebra, analyzed by semiquantitative spectrographic methods.
Sediment magnetic and paleomagnetic studies were conducted on a core from Buck Lake, Klamath County, Oregon, that was collected as part of an investigation into the Quaternary climate history of the western United States. This report documents the method
Sediment magnetic, paleomagnetic and geochemical results have been obtained from lacustrine sediments recovered in a 30-meter core taken by rotary drilling methods at Grass Lake, Siskiyou County, California. The data have been analyzed and interpreted in
This text file contains chemical analyses for 31 samples collected from various phosphate mine sites in southeastern Idaho (25), northern Utah (2), and western Wyoming (4).
This metadata file accompanies a report about the results of a study of the heavy minerals in samples collected from beaches and seafloor locations in the Palos Verdes margin, south of the Los Angeles area, California. Samples were collected from 11 beac
Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
