Expanding Horizon of the Astrobiogeochemistry of Transition Metal Stable Isotopes

Abstract

Astrobiogeochemistry of transition metal stable isotopes has been rapidly growing. Because of occurrences of large isotope fractionations associated with biological processes and minimal isotope fractionations during high temperature-pressure metamorphisms, transition metal stable isotopes have a potential to be used as a tool to detect biological activity and trace past biogeochemical cycles of the elements. Its overview and future perspective will be given in the talk.
