Description
The U.S. Geological Survey (USGS) is seeking a contractor to provide apatite fission-track (AFT) and U-Pb analyses from geological samples. The contractor will be required to have experience in all aspects of AFT+U-Pb thermochronometry using conventional track counting techniques, established calibrated against community standards, 252Cf irradiation, and LA-ICP-MS methods. The contractor will provide deliverables in a report in Excel spreadsheet format that includes raw spontaneous fission-track counts and count area, associated kinetic parameters, and final calculated AFT and U-Pb dates.
The key aspects of this job include:
• AFT+U-Pb thermochronometry using conventional track counting techniques
• 252Cf irradiation and LA-ICP-MS methods
• Experience with sample preparation and characterization
• Ability to provide deliverables in a report in Excel spreadsheet format
• The total work order is for 20 mineral separates and 25 total AFT+U-Pb analyses
