V022:
Microstructural Geochronology; New Records of Earth and Solar System Evolution Down to Atomic Scale





Session ID#: 26124

Session Description:
The link between planetary processes and nano-scale mineral properties has relevance to all fields of geology. This is increasingly the case with time information from microminerals which is critical to evaluating everything from rates and conditions of tectonic deformation to the chronology of impact events and the habitability of planetary crusts. The integration of radiometric dating (e.g., U-Pb) with orientation and chemical microstructures revealed using techniques such as EBSD, CL, TEM, SIMS and atom probe tomography is a growth area that continues to improve our temporal resolution of processes on the Earth, rocky planets and asteroids. This session will coincide with the launch of the AGU monograph “Microstructural Geochronology” and welcomes all high precision spatial and isotopic geochronology studies that better resolve the timing or sequence of important processes in our planetary past using mineral archives.
