Granites of Narketpalle area are located close to Hyderabad have been selected for a systematic study. Petrographic studies are carried out on granites include modal analysis. These studies indicate that the original magmatic structures have been completely obliterated, because of the onset of subsequent petrogenetic processes. Further, replacement structures and textural intergrowth of perthite and myrmekite are commonly observed. Seventeen representative granite samples were subjected to major elemental analysis and 6 samples have been analysed for trace elements. The data obtained and plotted various binary, ternary diagrams and trends of the major oxides and trace elements are observed. Geochemical variation diagrams do not indicate any definite origin for the granites of the investigated area.
