B--USGS Paired Bulk Mineralogy/Clay Analyses

The U.S. Geological Survey (USGS) Geology, Energy, and Minerals Science Center (GEMSC) required services for paired bulk mineralogy and detailed clay analysis by way of X-ray diffraction analysis. The proposed work will allow the relationship between clay mineral species and porosity to be fully assessed. The USGS is aware of no other source that can provide the above. Therefore, it intends to make an award to QMinerals unless it is contacted by any vendor who believes they have similar technical expertise and can provide the same service(s). Vendors are invited to contact the Contract Specialist, Miranda Blankenship, via email at [email protected] no later than 1:00 PM EST, Tuesday, November 10, 2026, with an affirmative answer.
