Combined AFT + U-Pb Dual-Dating Laboratory Services

The contract seeks laboratory services to perform integrated apatite fission track and uranium-lead dual-dating analyses on the same population of apatite grains, enabling precise thermal history modeling through coordinated analytical workflows. This requires specialized equipment and expertise to ensure spatially correlated measurements, where both dating techniques are applied sequentially or simultaneously to individual grains, preserving the integrity of the sample and the reliability of the resulting thermal interpretations. The work demands strict methodological alignment to avoid data discrepancies and to support robust geochronological reconstructions. This subcontract, classified under NAICS code 541380, is issued by the Department of the Interior’s Office of Acquisition Grants, with a response deadline of August 3, 2026. The solicitation does not specify a set-aside classification or point of contact, and performance location details are not provided. Interested parties must submit proposals by the stated deadline to qualify for award, with the expectation that the service provider can deliver high-precision, co-registered AFT and U-Pb data in a format suitable for advanced thermal modeling applications.
