Scope 
Reliable reconstruction of geohistory is of primary importance to better envision the present and future of the Earth.  Geochronology and isotope geology play major roles in the reconstruction.  This session offers an opportunity to present the results of fundamental studies, including the developments / improvements of analytical methods and age calibration, as well as applications to the Earth and planetary materials.  We particularly focus on: (1) radiometric dating, bio-stratigraphy, magneto-stratigraphy and stable isotopic time series that provide the age information, (2) radioisotopes and stable isotopes widely employed for analyzing the Earth and planetary systems and (3) hypothesis and numerical modeling that utilize / assimilate the age and isotopic data.  We also welcome contributions that integrate a variety of relevant disciplines.
