What the buyer needs

AI summary

The U.S. Geological Survey Geology, Energy, and Minerals Science Center requires paired bulk mineralogy and detailed clay analysis via X-ray diffraction analysis for 58 rock samples. The scope entails quantitative mineralogical analysis for bulk crystalline phases and amorphous content, clay fraction quantification of clay mineral species, sample preparation, XRD measurement, data interpretation, and delivery of methods and Excel reports within two months of receiving samples. USGS intends to award this contract to QMinerals because it knows of no other capable source. Any vendor possessing similar technical expertise must contact Contract Specialist Miranda Blankenship by email no later than 1:00 PM EST on Tuesday, November 10, 2026, with an affirmative response. The period of performance is two months from the date of award at the vendor's laboratory.
