Brief Description (Abstract):

Mineral chemical data of selected rock types of Schirmacher range East Antarctica are presented. Some of these rocks have strong petrological comparisons to south Indian leptynites and Khondalites. Temperature estimate based on the Fe-Mg calibrations of co existing garnet biotite mineral pairs suggested that metamorphic temperatures varied from 550 750?C. Geo barometer calibration of gar-sil-plag-qtz yielded an estimate of 5 31k bar at 600 ?C for khondalites.

Status: Completed

Purpose: Recent third Indian expedition to Antarctica carried out mapping of 35 sq km of Schirmacher Range of East Antarctica (Sengupta 1985). The rock types recorded were calc silicates pelitic gneis-ses charnockites meta basics and migmatitic variants of gneisses. Several late granites and basic dykes were also noted. Detailed field and petro graphical account of the rock types are given in Sen-gupta(1986). In this paper some preliminary work carried out on the mineral chemistry and metamorphism of selected rocks of Shirmacher Range is presented.
