Quick Summary
The U.S. Geological Survey (USGS) is conducting market research through a Sources Sought announcement to identify qualified businesses capable of providing geochronologic analyses. Specifically, the USGS Alaska Science Center requires high-quality 187Re/187Os analyses of sulfide minerals for various research studies. This opportunity is designated as a Total Small Business Set-Aside. Responses are due by April 16, 2026, at 8 AM Pacific time.
Scope of Work
The objective is to perform 187Re/187Os geochronology on approximately 32 samples, including molybdenite, pyrrhotite, or arsenopyrite-bearing mineralization. The scope encompasses sample evaluation, preparation, analysis, and the provision of full electronic reports with data and interpretation. Contractors must possess a strong background in applying 187Re/187Os geochronology to geological problems, particularly with arsenopyrite, pyrite, and molybdenite. The laboratory must be known for high-quality work, utilizing uniform practices in sample handling, preparation, and mass spectroscopic analysis. Analysis requires a mixed Re-double Os spike and state-of-the-art Triton thermal ionization mass spectrometers. The senior researcher/director must be an ore geologist with advanced degrees and expertise in ore systems, Re-Os, and U-Pb zircon geochronology. All data produced will belong to the Government and is intended for public release.
