Isotope and Chemical Methods for Mineral and Geoenvironmental Assessments and Support of USGS Science Strategy

This Project integrates several geochemical tools—stable isotope geochemistry, noble gas geochemistry, active gas geochemistry, single fluid inclusion chemistry, and fluid inclusion solute chemistry—in studies of the processes that form mineral deposits and the processes that disrupt them during mining or natural weathering. Research is directed toward fundamental scientific questions or, in...

Argon Geochronology

This project supports the USGS argon geochronology laboratory in Denver. The USGS 40Ar/39Ar geochronology laboratory is a state-of-the-art research facility for determining absolute ages of minerals and rocks. The 40Ar/39Ar laboratory contributes critical geochronology to individual USGS research projects and to partners in academia and other Federal...

Research Mineralogy - X-ray Diffraction Lab

The primary goal of this project is to ensure the availability of state-of-the-art mineralogical analyses and, when needed, development of new analytical methods that can be applied to topical studies in Energy and Minerals Mission Area, as well as the other mission areas.

The project includes mineralogy by X-ray diffraction (XRD), qualitative and semi-quantitative x-ray fluorescence...

From Outcrop to Ions: development and application of in-situ isotope ratio measurements to solve geologic problems

Project objectives are to (1) develop innovative analytical techniques for isotope geochemistry and U-Pb geochronology using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and (2) apply these techniques to collaborative research projects of high priority to the Mineral Resources Program, including studies related to the formation of "critical mineral" deposits, and...
