B--Split-Stream Zircon Petrochronology Analysis

The U.S. Geological Survey (USGS) is conducting market research to determine the availability of qualified businesses capable of providing zircon petrochronology analysis services. The requirement consists of analysis of approximately five rock samples to generate U-Th-Pb and Lu-Hf isotopic data in support of geologic research. The work includes preparation of rock samples, imaging and characterization of zircons, split-stream laser ablation analysis, and generation of analytical datasets. • The contractor shall have experience in all aspects of mineral separation and zircon petrochronology using LASS methods. • The contractor shall provide deliverables in a report for each sample in spreadsheet format, with both the raw and interpreted data included. • The contractor shall ship the mineral separates and any unprocessed, left-over rock to USGS. • The USGS will ship intact rock samples to the vendor in one shipment. • Analyses will be completed at the vendor’s facility.
