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,...

Tellurium in Igneous-related Epithermal Precious Metal Deposits in Colorado and New Mexico

The project aims to improve our understanding of the causes of tellurium enrichment in epithermal precious metal deposits, and strengthen our ability to assess the Nation's tellurium deposits. Tellurium is used in solar panel technologies and is considered a critical mineral. Epithermal deposits of this type represent a prospective future source of tellurium.
