Geochemical data supporting a comparison of apatite between regional magmatism and the Pea Ridge Iron Oxide-Apatite-Rare Earth Element (IOA-REE) and Boss Iron Oxide-Copper-Cobalt-Gold-REE Deposits (IOCG) deposits, southeastern Missouri, USA

High-spatial resolution geochemical analyses of Mesoproterozoic apatite crystals in igneous rocks from this area to elucidate the petrogenetic histories of the samples and help evaluate ore deposit models. Data are provided in CSV format.

Whole-rock and sulfide-mineral geochemical data for samples from volcanogenic massive sulfide deposits of the Bonnifield district, east-central Alaska

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

In situ geochemical data related to the gold-quartz veins of Grass Valley, California, 2014-2015

Geochemical data for pyrite crystals and native gold from two distinct vein sets in this area to better understand paragenesis of quartz veins in orogenic gold deposits. Data are provided in CSV format.

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) geochemical data for apatite grains in rocks and stream sediments from the Taurus porphyry copper deposit area, eastern Tanacross quadrangle, Alaska

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses of apatite provide trace element concentrations that support indicator mineral studies in this deposit. Data are provided in CSV format.

Geochemistry of magnetite from porphyry Cu and skarn deposits in the southwestern United States

Hydrothermal orebodies and their host rocks are characterized by compositional variations in magnetite. Minor and trace element data for hydrothermal and igneous magnetite are compared with an unmineralized magnetite-series granodiorite in southwest Japan

Geochemical data for the Elk Creek alkaline complex, southeast Nebraska

Analytical data from a suite of rock and mineral samples collected from drill core within the Elk Creek alkaline complex, which hosts the Elk Creek carbonatite, a multilithologic carbonatite enriched in niobium, rare earth elements (REEs), scandium, and titanium. Data are provide in CSV format.

Global Geochemical Database for Critical Minerals in Archived Mine Samples

Chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States and from archetypal deposits from 27 other countries. Data are provide in Microsoft Access, Microsoft Excel, and CSV formats.
