Structural and Geomorphological Evolution of ...

Eastern Dharwar Craton in Narella area of Karimnagar district (India) is studied using GIS, remote sensing and planar fabric preserved in high grade metamorphic rocks and structural deformation in their associated igneous dykes and supracrustals. Two distinct phases of deformation characterized with F1 and F2 plunging folds have given rise to ENE-WSW and NNW-SSE aligned ridge and valley system often dislocated by strike slip faults. Structurally controlled drainage, vertical scarps, shattered residual hillocks point to a rejuvenated topography undergoing slow and steady transformation under accumulating stresses in the area. Such tectonically controlled features demand for a reappraisal of seismic hazard zonation assessment in the area.
