Abstract: Remote sensing is a technique to study characteristics of area in respect to structures, alteration, and lithological variations by measuring its reflected and emitted radiation from distance (satellite or aircraft). In this study the ASTER and ASTERDEM data has been used for identifying mineral alteration zones, major lineaments, structures, and lithology through different band ratios, band math techniques. Further, Delineation of hydrothermal alteration Zones inclusive of Phyllic, Argillic, Prophyllic, Iron, carbonate, host rock alteration, Chlorite, sericite alteration etc. also been attempted. The study area is located in Sirohi district of Rajasthan and geologically falls under SDFB (South Delhi Fold Belt) of the Delhi Supergroup. The area composes of various rock types like Granite/Gneiss, Amphibolite, Schists (Chlorite, Qtz - Biotite, and Sericite), Limestone/marble and quartzites.

Keywords: Aster Data, South Delhi Fold Belt, Mineral Alteration, Band ratio techniques
