REMOTE SENSING AND GIS TECHNIQUES FOR URBAN GEOLOGY & HYDRO GEOLOGICAL STUDY

Abstract: Geologically the study area forms a part of the Indian peninsular shield and comprises Archaean and Proterozoic formations, characterized by igneous rocks, sedimentary rocks and their variants. The peninsular shield has been stable for the last 1000 m.y. However, during mountain building activity in the early Precambrian orogeny, the rocks have been subjected to folding, faulting, uplifting, metamorphism, intrusion and extrusion. Followed by this activity Proterozoic basins were initiated. The uplifted highlands of Precambrian and associated intrusives have been the source for these sediments. In this way the Precambrian shield and the Proterozoic sedimentary complex have formed a complex geological set-up, providing a unique geology in the study area.
