Radiogenic Isotope Analyses

The U.S. Geological Survey's Western Mineral & Environmental Research Science Center is soliciting quotations for radiogenic isotope analyses, specifically whole-rock strontium-hafnium-lead-neodymium isotope geochemistry services. This is a firm fixed-price purchase order solicitation using simplified commercial acquisition procedures under FAR Parts 12 and 12.603, subject to the Service Contract Act. The contractor must maintain an internationally recognized laboratory with demonstrable expertise in these isotope analyses and employ a lead isotope geochemistry expert holding a Ph.D. and at least five years of additional experience with peer-reviewed publications in the field. Evaluation will be based on technical capability to meet Statement of Work requirements, relevant past performance based on recent similar work and references, and price reasonableness, with non-price factors weighted approximately equal to price. Quotations must be submitted electronically to Anthony Berry at amberry@ios.doi.gov by April 16, 2026 at 0800 Pacific Daylight Time.

This solicitation is designated as a Total Small Business set-aside, restricting competition to qualifying small business entities. The work involves analyzing 30 pulverized whole-rock samples collected from Cretaceous Ural-Alaskan-type ultramafic complexes in southeast Alaska to support critical mineral research, with all analytical results and a comprehensive report detailing techniques, data reduction methods, and uncertainties to be delivered within the 12-month period of performance commencing April 22, 2026 and concluding April 21, 2027. The contractor must provide all necessary staff and equipment and submit payment requests electronically through the Department of Treasury's Internet Processing Platform. No specific award value or budget range has been disclosed in the solicitation notice. The place of performance is not explicitly specified; however, the contractor's laboratory must be internationally recognized and capable of conducting the specified isotope analyses.
