Summary
The U.S. Geological Survey is soliciting offers from small businesses to prepare approximately 440 microbe-polished thin sections from rock samples, including cutting, mounting, polishing, staining when requested, and engraving sample numbers on the slides. The work supports USGS geological research concerning the tectonic, magmatic, and metallogenic evolution of the Yukon-Tanana upland in eastern interior Alaska, with performance at CSUS Sacramento from September 30, 2026, through September 30, 2028. This is a small-business procurement solicitation, not a grant program; offerors must provide three recent academic or government researcher references and meet specified quality requirements.
