[S3-07] Anticlockwise pressure-temperature path for the Zavkhan eclogite in the NW Mongolia
Keywords:Anticlockwise pressure-temperature path, Eclogite, Blueschist
Contrary to the prograde-type P-T path, recent investigation has revealed that some eclogites in Chiles, Fransciscan, Mt. Zagros and NW Mongolia transformed from high temperature amphibolite by anticlockwise P-T path. I would like to present a detailed petrochemical data and Raman geobarometer data for the Zavkhan eclogitein the NW Mongolia. It will be shown that the former kyanite-bearning amphibolite paragenesis (>600 ºC) were transformed into epidote eclogite equilibrated at 480 ºC and 2GPa by anti-clockwise P-T path.
