Abstract

We estimated P-T conditions of the metamorphic rocks from the central and the western Sør Rondane Mountains, Antarctica, by using conventional geothermobarometers. Estimated temperatures are about >800 degC around Brattnipane and southern Austkampane, and decreased rapidly toward the south. The thermocline is roughly coincident with the Sør Rondane Suture. Estimated pressures are about 8-9kbar around Austkampane and northern Lunckeryggen, and decreased toward south and northeast. The zone where the pressures rapidly change runs roughly along the Main Shear Zone.
