Modelling of Metamorphic Textures with C-Space: Evidence of Pan-African High-grade Reworking in the Eastern Ghats Belt, India


The polymetamorphic Eastern Ghats Belt, India is an important component of models predicting Indo-Antarctic correlation in the Precambrian. However, the metamorphic signatures developed during the Pan-African orogeny are hardly known. Here we address this issue through modelling of reaction textures developed in a massif-type anorthosite from Chilka Lake area using the programme C-Space. We have explained the metamorphic textures in terms of balanced chemical reactions, which revealed at least two stages of mineral reconstitutions during the Pan-African event.
