Data collected to determine geologic background concentrations of trace metals in water and stream sediment, and to quantify the increase in dissolved constituents in streams attributable to historical mining activity in this area. Data are provided in CSV format.

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

The data consist of major- and trace-element whole-rock geochemical analyses and major- and trace-element analyses of sulfide minerals determined by electron microprobe and laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) techniques

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.

This report presents geochemical analyses for 210 unaltered and unmineralized rock samples of Paleozoic age in the western Brooks Range of northern Alaska.

Whole rock chemistry on 185 samples, mostly from Au prospects, with lesser samples from porphyry Cu prospects in this area. Data are provided in CSV and shapefile formats.

Whole rock major, minor, and trace element geochemical data from outcrops, waste rock piles, and drill core from the upper part of this deposit, the associated base metal vein system, and the surrounding hydrothermally altered to unaltered country rock. Data are provided in CSV format.

Geochemical, x-ray diffraction mineralogical, and electron probe microanalysis (EPMA) data on rocks, soils, and sediments collected near porphyry copper deposits in this area. Data are provided in CSV format.

Locations and characteristics of the copper smelters throughout the world as of 2002.

Geologic and mineral resource information for 1635 deposits of phosphate worldwide

Relational database describing 102 materials from the early 1800s to circa 2017 through anthropogenic cycles, their recycling and criticality properties, and on spatial scales ranging from suburbs to global. Provided as MySQL, PostgreSQL, and CSV formats.

Zirconium and hafnium are corrosion-resistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon or as zirconium oxide or other zirconium chemicals.
