• Subject Area: Mineralogy, Petrology and Geochemistry
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 268236062

The objective of this project is to provide timely, state of the art analyses of cosmogenic nuclides and radiocarbon, U-Pb as well as U-Th disequilibrium dating, for members of the CRC. Results of methodological developments achieved in D02, D03 and D04 are hereby directly accessible for pioneering research. Ten of the twenty envisaged scientific subprojects require cosmogenic nuclide and radiocarbon analyses to obtain essential information on chronology and process rates, measured by Accelerator Mass Spectrometry (AMS) and Multicollector Noble Gas Mass Spectrometry (MC-NGMS). Nine subprojects will utilize the isochron-based U-Th disequilibrium, solution U-Pb and Laser ICP-MS dating method. This precise and accurate U-Th and U-Pb isotope ratio measurements of nanogram sample material is measured by Multicollector Inductively Coupled Plasma Mass Spectrometry (MC-ICPMS). In situ U-Pb analyses by laser ablation (LA) MC-ICPMS, which will be developed in the first 12 months of D02 project, will allow high sample throughput and high dating success rate due to high spatial resolution with microgram sample material.
