Brief Description (Abstract):

Occurence of several morphologies of quench olivine textures in a basaltic dyke is reported from Antarctica for the first time. This basaltic dyke occurs in the Precambrian poly metamorphosed gneissic terrian of Schirmacher Oasis, Queen Maud Land, East Antarctica. The morphologies of quench olivines in this basaltic dyke suggest that they were formed by rapid cooling of the magma at 15-40? c/hour. Further, the delicate nature of the quench olivine, which are mostly confined to the glassy margins of the dyke suggest their in situ crystallisation.

Status: Completed

Purpose: To study a basaltic dyke which is characterised by the occurrence of several morphologies of quench olivine textures, is being reported from Schirmacher Oasis, Queen Maud Land, East Antarctica.
