Abstract
The terrain between the Godavari river in the south and the Mahanadi river in the north, comprising about 50,000 sq. km area forms the study region. LANDSAT imagery and aerial photographs were studied with a view to delineate the fracture patterns and analyse their possible significance. The frequency azimuth rose diagrams of fractures indicate two sets of preferred orientations in ENW-WSW and E-W directions. The possibility of some of these fractures/fracture traces being relatively very much younger to the main Eastern Ghat orogeny is a tentative surmise made from this study. These younger fractures may be related to a cymatogenic upwarp during mid-Tertiary.Downloads
