Overview of chemical analyses, tracer studies, gas geochemistry, stable isotopes analyses, organic chemistry, and thermometry capabilities at major USGS laboratories with links to technique, equipment, and contacts for each procedure.
Maps and text (Word or PDF format) and database (Excel or HTML format) for bedrock, forest floor, and mineral soil sampling in Voyageurs National Park, Minnesota to establish the background and baseline geochemistry and terrestrial mercury sources.
Description of the Denver Organic Geochemistry Laboratory where chemical and geological data is used to research the physical and chemical processes of hydrocarbon generation, migration and accumulation, with links to programs, personnel, and products.
The Organic Geochemistry Research Group of the Kansas District focuses on the fate and transport of organic contaminants in the environment with links to objectives, analytical methods, laboratory methods, publications, events, photos, and personnel.
Site to obtain currently available geochemical reference materials, certificates for reference materials no longer available, reference materials in production, and order and processing information. Some documents in PDF format.
Manual of chemical sediment analysis using Coulometer and CHN Analyzers to measure carbon content, spectrometric analysis for biogenic silica, and radiochemistry to measure isotopes. Includes techniques,sample preparation, and safety procedures.
Coordinated studies of the effect of historical mining for mercury, origin and composition of metals in groundwaters and surface waters, history of volcanic and intrusive activity, and the complex geological history of this area.
This report presents geochemical data generated during mineral and environmental assessments for the Bureau of Land Management in northern Nevada, northeastern California, southeastern Oregon, and southwestern Idaho, along with metadata and maps.
