Description
The USGS Geology, Minerals, Energy, and Geophysics Science Center requires whole-rock samarium-neodymium, uranium-lead, and rubidium-strontium isotope analyses of samples collected from mafic-ultramafic igneous and evolved intrusive igneous rocks. The contractor will provide isotope analyses using recognized spikes, separation methods, standards, and instrumental techniques to meet the typical precision for analyses reported throughout the literature. The contractor must have a Ph.D. degree in isotope geochemistry and have 5 or more years of experience in the field. The lab must be an internationally recognized and reputable isotope geochemistry lab.
• The contractor will analyze 25 surface whole rock samples for Sm-Nd, U-Pb, and Rb-Sr analyses.
• The contractor will provide a report containing all relevant isotopic data, including elemental and isotopic concentrations of Sm, Nd, U, Pb, Rb, and Sr along with their uncertainties.
• The contractor will communicate with the USGS on a regular basis and in case of any unforeseen complications with the rock samples submitted.
• The period of performance will be approximately 12 months from the award of the contract.
• The contractor must be registered and have an active registration in the System for Award Management (SAM) at the time of submitting a quote to be considered for an award of a federal contract.
