Geochemical analyses of soils and sediments, Coeur d'Alène drainage basin, Idaho: Sampling, analytical methods, and results.

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 Data from Quaternary Lacustrine Sediment in Two Cores from Tule Lake, Siskiyou County, California

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

Whole Rock Geochemical Data For Paleozoic Sedimentary Rocks of the western Brooks Brooks Range, Alaska

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

Whole rock geochemical data for altered and mineralized rocks, Red Dog Zn-Pb-Ag district, western Brooks Range, Alaska

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

Chemical data for rock, sediment, biological, precipitate, and water samples from abandoned copper mines in Prince William Sound, Alaska

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

Major- and trace-element concentrations in soils from northern California: Results from the Geochemical Landscapes project pilot study

Regional-scale geochemical survey designed to serve as a baseline for further analyses, and to understand effects of historical mining in the area.

Analytical results for stream sediment and soil samples from the Commonwealth of Puerto Rico, Isla de Culebra, and Isla de Vieques

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 Data from Buck Lake, Oregon

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 and Paleomagnetic Data from Buck Lake, Oregon

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).

Heavy minerals from the Palos Verdes margin, southern California: Data and factor analysis

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

Case study of the environmental signature of a recently abandoned, carbonate-hosted replacement deposit: The Clayton Mine, Idaho

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.
