Owing to recent advances of mass spectrometry for high-speed data acquisition, chronological data are increasingly available, especially for zircon U-Pb ages. Toward elucidation of geological processes utilising big data of zircon U-Pb ages, the combination of chronological data and data obtained from various research fields, such as geology and geochemistry, can become a powerful tool. Hence, high-speed acquisition of geological and geochemical data along with chronological data is important, and, for instance, improvements in elemental imaging analysis to derive geochemical data is desired.
Despite the importance of zircon, zircon ages can record only limited geological processes depending on the occurrences of zircon and the nature of the zircon U-Pb system. Thus, our next move is to devise innovative approaches for radiometric dating methods to extend the applicable ranges of ages and materials. Reflecting on the meaning of radiometric ages derived from various minerals, and the development of dating methods for the minerals are essential for unveiling mechanisms of geological processes.
In this session, we propose Hybrid Geochronology that integrates insights provided by multiple dating methods for various materials, and research presentations from all aspects of geochronology are welcomed.
