PETROLOGY AND GEOCHEMISTRY OF GRANITES IN AND AROUND NARKETPALLE MANDAL, NALGONDA DISTRICT, T.S., INDIA
Journal Title: Bulletin of Pure and Applied Sciences Sec. F –Geology - Year 2018, Vol 37, Issue 1
Abstract
Granites of Narketpalle area are located close to Hyderabad, have been selected for a systematic study. Petrographic studies and nodal analyses were carried out on granites of Narketpalle area to decipher the crustal evolution. 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 six samples have been analysed for trace elements. The data obtained and plotted for 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.
