Cooling rate of regional metamorphic rocks in Japan and exhumation mechanism of the metamorphic belt

Study period:1982 - 0

Research overview:
Cooling rate of regional metamorphic rocks is decided by the analysis of formation temperature and K-Ar age of minerals, and then exhumation rate of rocks is argued with decided cooling speed. On the basis of these analyses, exhumation mechanism of regional metamorphic belt is examined. This study makes it possible to clear real metamorphic field in the mobile earth.
