The objective of this project is to provide timely, state of the art analyses of cosmogenic nuclides and radiocarbon, 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. 10 of the 20 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). 9 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). These analyses (i.e. AMS, MC‐NGMS & MCICPMS) have in common that specialist sample preparation is needed to transform samples into a suitable form for measurement. 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 hopefully also high dating success rate due to high spatial resolution with microgram sample material. Furthermore, specialist knowledge is required to interpret the results.
This project is to provide the required capacity to perform routine, high quality analysis for the several hundred samples of the planned CRC, and the expertise for sampling and interpreting the data as service to the CRC projects.
Phase 1
Research areas: Geochemistry
Nine of the nineteen envisaged scientific subprojects require cosmogenic nuclide and radiocarbon analyses to obtain essential information on chronology and process rates. These analyses have in common that they require Accelerator Mass Spectrometry (AMS) and prior specialist sample preparation to transform samples into a suitable form for AMS-measurement.
This project is to provide the required capacity to perform routine, high quality analysis for more than 1000 AMS-samples of the planned CRC and the expertise for sampling and interpreting the data as service to the CRC projects.
