Abstract: In this study, different digital format data sources including aeromagnetic and remotely sensed (Landsat 8 and ASTER) images were used for structural and tectonic interpretation of the Mahabubnager and Gulbarga districts of Telangana and Karnataka states in the Eastern Dharwarcraton. From analysis of Landsat and ASTER images, the surface morphology and major lineaments trending in the NW–SE, E-W and NE-SW were identified. Qualitative analysis of IGRF corrected aeromagnetic data were carried out using the analytical signal, reduction to pole, horizontal & vertical gradient maps, several lineaments trending in three major directions NE-SW, NW-SE and E-W were delineated.
