Split-Stream Zircon Petrochronology Analysis

The U.S. Geological Survey Office of Acquisitions and Grants is conducting market research through a Sources Sought Notice for split-stream laser ablation zircon petrochronology analysis services, with capability statements due by July 8, 2026. No set-aside is anticipated.

Work will be performed at the vendor's facility. The USGS will provide intact rock samples in a single shipment for zircon mineral separation, imaging, characterization, and split-stream laser ablation analysis to generate U-Th-Pb and Lu-Hf isotopic data for approximately five rock samples. Vendors must demonstrate laboratory capabilities with split-stream LASS experience, instrumentation including laser ablation systems and mass spectrometry, and geochronology or geochemical analysis expertise. The contract requires ability to perform a minimum of 50 analyses per sample and deliver raw and interpreted results in spreadsheet format with full analytical documentation.

Interested vendors must submit capability statements addressing laboratory capabilities, instrumentation and analytical methods, relevant experience with recent work examples, quality assurance and quality control procedures, data deliverable formats, and company information including business name, UEI number, SAM registration status, and business size classification. Responses should be sent to joel_berberena@ios.doi.gov.

The applicable NAICS code is 541690 (Other Scientific and Technical Consulting Services) with a $19.0 million size standard. PSC is B517 (Special Studies/Analysis—Geological). This notice is for information and planning purposes only; responses will be used to determine acquisition strategy and do not constitute a solicitation or obligation to award.
