Sample locations and descriptions, with compositional analysis to constrain the natural background levels of fibrous amphiboles potentially derived from the nearby Rainy Creek Complex.

The Southern High Plains (SHP) is a new and emerging U.S. uranium province. Here, uranyl vanadates form deposits in Pliocene to Pleistocene sandstone, dolomite, and limestone

Preliminary information about the concentration, spatial distribution and mineral hosting of metals and other elements in solid materials at the Elizabeth copper mine after 50 years (or more) of weathering and oxidation.

Approximately 400 young children have died and thousands more are affected. This study clarifies lead sources and exposure pathways, identifies other toxicants of concern and people at risk, and examines potential for similar lead poisoning globally.

Morphological data on fibrous mineral particles from an old vermiculite mine that has been a subject of environmental health investigations

Descriptions and analytical data (electron microprobe, X-ray diffraction, spectral reflectance, and scanning electron microprobe analyses) for unexpanded and expanded vermiculite samples, a mineral product with commercial applications. Data are provided in CSV format. Descriptions of the samples are provided as PDF reports.

Investigates Cr and Ni geochemistry providing insight into the mobility and bioaccessibility of these toxic trace elements throughout northern California and perhaps the origin of elevated dissolved Cr(VI) concentrations in the western Sacramento Valley
