Quantitative chronological data derived from radioisotope dating methods is essential for elucidating the mechanism of geological and cosmological phenomena. Recent advances in mass spectrometry utilised for radioisotope dating methods have led to the acquisition of high-quality and large-quantity chronological data, resulting in the establishment of new research fields including chronological cytometry and multi-geochronology. However, comprehending the true meaning of radioisotope dates is challenging without wisdom from multiple geoscience fields (geology, geophysics and geochemistry).
In this session, hence, we propose Hybrid Geochronology that integrates insights provided by geochronology and various research fields, and groundbreaking research presentations from all aspects of geochronology are welcomed. Through the past two sessions in this series, we are aware of the necessity of not only the novel development of radioisotope dating methods, but also observations in macroscopic and microscopic scales from outcrops to thin sections and trace-element imaging analysis. We hope to create an opportunity for discussing new research approaches from original viewpoints.
