An area of about four hundred and eighty square kilometres in Visakhapatnam, consisting of khondalites, charnockites and granites, was geologically mapped. The trend of the formations varies from NE-SW through E-W to NW-SE. This trend neither conforms with NE-SW trend of the Eastern Ghats nor with the NW-SE trend of the hinterland of the Eastern Ghats between the Godavari and Mahanadi rivers. The change in the trend pattern is inferred to be due to the area being located in an intensely folded and faulted region in the eastern margin of the Eastern Ghats.

Abstract


An area of about four hundred and eighty square kilometres in Visakhapatnam, consisting of khondalites, charnockites and granites, was geologically mapped. The trend of the formations varies from NE-SW through E-W to NW-SE. This trend neither conforms with NE-SW trend of the Eastern Ghats nor with the NW-SE trend of the hinterland of the Eastern Ghats between the Godavari and Mahanadi rivers. The change in the trend pattern is inferred to be due to the area being located in an intensely folded and faulted region in the eastern margin of the Eastern Ghats.
