Geological and Chemical Classification of the rocks of the Bundelkhand Granitoid Complex

Abstract

The Bundelkhand Granitoid Complex exposes three variants of the granites namely, pink, porphyritic granite, pink medium grained granite and greyish-white, medium to coarse grained granite. Based on modal distribution of specific minerals (K-feldspar, plagioclase feldspar and quartz) they all fall in the category of syenogranites as per IUGS nomenclature. Detailed petrological and chemical examination of these rocks has been attempted to understand their origin, the nature of the parent magma and the associated mineralization process.
