Laboratories

This project provides Mineral Resources Program scientists with access to state-of-the-art analytical laboratories and expertise to advance the Program mission. The project also develops new analytical techniques and methodologies to improve data quality and geological interpretations for USGS scientists.

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 agencies. This laboratory develops methodology...

The Project objective is to facilitate the full potential of stable isotope (C,H,N,O,S), noble gas isotope (He, Ar, Ne, Ar, Kr, Xe), active gas geochemistry (CO2, H2S, SO2, CH4, HF, HCl, N2, H2, organics, light hydrocarbons), and solute geochemistry measurements of minerals and fluids (including single fluid inclusions) in multidisciplinary studies of fundamental processes that affect mineral...

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...

The project objective is to develop and apply solution and in situ isotopic and trace element methods to emerging research opportunities to gain a better understanding of the processes controlling critical mineral deposits, metal mobility, and other geological inquiries.

The project objective is to determine the processes responsible for critical element enrichment in carbonatites and to enhance our ability to identify and assess economic deposits. This project will work at various scales to meet this objective and will primarily focus on deposits within the US or our Critical Minerals Mapping Initiative collaborative Nations Canada and Australia.

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 spectroscopy...

TThe USGS Denver Microbeam Laboratory provides critical analytical and characterization support for a wide variety of internal USGS projects and external collaborators. In addition, the lab continually works to develop new methods or improve existing methods to analyze a variety of sample matrices.
