Research Abstract

The main target of this research program is to consider the details of various extreme metamorphic processes during the whole Earth's history and to understand the geological processes in deep portion of "Orogen". During the 4-years research, close microanalyses of very fine micro-inclusion minerals and fluid-inclusions, and also micro-geochronology were carried out. Results are published as 50 journal papers as analyses of micro-domain metamorphic process and detailed P-T-t paths of various orogenic systems.
