Cathodoluminescence response of barite at room and liquid nitrogen temperatures

Rare earth element (REE) enrichment in the Elk Creek carbonatite, Nebraska USA, is comparable to ore grade enrichment in carbonatite-hosted REE deposits[1]. Petrographic examination of textures documents a complex history of crystallization, brecciation, recrystallization, oxidation, and near surface alteration. Barite (BaSO4) is present in most units, including REE-enriched zones, such that it ma

Demonstration of a novel quantitative microscopy technique for automated characterization of in situ particulate matter in coal miners with progressive massive fibrosis

Rationale: Increasing exposure to respirable crystalline silica (RCS) linked to changes in mining production processes has been implicated in the resurgence of severe lung disease in U.S. coal miners. Lung mineralogy can provide insight into particle pathogenesis. However, standard approaches to characterizing in situ particulate matter (PM) by pulmonary pathologists have poor inter-rater comparab

Trace Elements in Quartz, Rutile, and Zircon

Quartz is an ubiquitous mineral that forms in all geologic environments including diagenetic, metamorphic, plutonic, and volcanic settings. Quartz is relatively unreactive and is likely to preserve its geologic history. Trace elements in quartz offer clues to formation temperatures and pressures, fluid chemistry, and tectonic setting. Rutile and zircon are refractory minerals also found in a...

Rare Earth Element Microanalysis

Rare earth elements (REE) are critical elements in the technology and energy production sectors as they are used in everything from smartphones to wind turbines. The demand for these materials has seen steady growth and production is lagging. The laboratory supports several projects within the USGS that are characterizing rare earth element minerals from Bokan Mountain and Dora Bay, Alaska...
