Geochemical characteristics of the granites of Bundelkhand massif, central India

The Bundelkhand massif comprises various types of granites. On the basis of field relations, three compositionally distinct granitic phases have been delineated. These are homblende granite, biotite granite and leuco granite in stratigraphic sequence. The major elements variations against SiO2 display smooth trends which should be expected for a composite massif evolved by fractional crystallization. The variations of incompatible elements compared to the compatible elements suggest a partial melting process for the evolution of the massif.
