Abstract

The Altai Orogen in the southwestern margin of the Central Asian Orogenic Belt contains various volcano-sedimentary rocks that were deformed and metamorphosed under various P-T conditions Geothermobarometric and mineral equilibrium modelling studies on the rocks obtained peak P-T condition of 640-690C /6.3-10.7 kbar and clockwise path from the area. Such high-pressure amphibolite-facies event is related to the activity of CO2-rich fluid.
