GEOCHRONOLOGIC RADIOGENIC ISOTOPE ANALYSIS

TITLE: Isotope Analysis of Lu-Hf and Sm-Nd for Geochronology of Garnet Samples The USGS Geology, Energy, and Minerals Science Center requires garnet geochronology on a suite of newly collected samples of metamorphic rocks from the upper Peninsula, Michigan. The Lu-Hf and Sm-Nd garnet ages of these samples will be helpful for ascertaining the timing of metamorphism and deformation of these rocks.

This information is essential for strengthening our understanding of the bedrock geology in the Upper Midwestern United states with new geochronologic constraints. The Lu-Hf and Sm-Nd isotope analyses will be done by isotope dilution. Refer to the Performance Work Statement for work requirements. This shall be a firm fixed-price purchase order with a performance period of 02/15/2024 - 02/14/2025.

The acquisition is being conducted under the Federal Acquisition Regulation (FAR) Part 13, Simplified Acquisition Procedures, and is open to all business size vendors. The NAICS code is 541990. Appropriate DOL Wage Determination for contractor location shall be incorporated into the award. The award will be made to the offer that is most advantageous to the Government based on technical capability and price. RFQ Sections E.4. and E.5. provide instructions and evaluation factors, respectively.
