Hyderabad granite region (HGR), is part of Eastern Darwar Craton (EDC) which has 2.5 billion years age and it covers an area of ~ 150 x 150 kms. HGR is considered as largest granitic pluton of Indian subcontinent. (S.B. Singh, et.al). Dolerite dyke formed in this Region of batholithic craton is composed mainly with granitic gneisses and unclassified granites. This region was apparently formed due to extensive lower crustal remelting of permobile phases of older (3.3-2.9Ga) gneisses (Divakara Rao, 1996). Dyke is crouped out to the west of Anisetti Duppalapally (A.D.P) village as boulders from various sizes and they are weathered. Few samples were picked during the field work for petrographical studies. The present study is aimed to understand the crystallization history of basic magma.
