B--USGS Detrital zircon U/Pb, Hf, and T/REE analyses
Solicitation # 140GG027Q0015
The U.S. Geological Survey (USGS) is seeking specialized analytical services for detrital zircon U/Pb, Hf, and T/REE analyses on rock and modern sediment samples. This work supports multiple scientific initiatives, specifically the Gulf of Mexico and Alaska Petroleum Systems Projects. The scope of work includes U-Pb geochronologic analysis for 100 to 300 zircons per sample, with the potential for 600 or more analyses upon request, followed by SC-ICPMS measurements of T/REE and Hf isotopic concentrations. Deliverables consist of formatted Excel spreadsheets containing age data, isotope ratios, and concentration measurements, accompanied by annotated BSE map images or data files indicating analysis locations. The contract requires the service provider to be a professional with at least a Master's degree in analytical geochemistry and continental tectonics. Technical performance must adhere to specific protocols from Gehrels et al. and Sundell et al., utilizing nondestructive methods with strict reproducibility standards for isotope ratios. The total performance period for all samples shall not exceed one year, with individual orders typically completed within one to three months. The USGS intends to award this contract to the University of Arizona LaserChron Lab as a sole source, though other qualified vendors were invited to respond by November 4, 2026. Final acceptance of the work is managed by a USGS Technical Liaison based on the completion of all required geochronologic measurements.
