Abstract

Lineaments numbering about 110, show two major preferred directions, i.e., northwest-southeast and northeast-southwest. Majority of the lineaments are believed to be of Archaean ancestry. The Precambrian Pakhal, Sullavai, and the upper Palaeozoic to Mesozoic Gondwana sediments were deposited largely in a fault-controlled, successively developed troughs, broadly trending in a northwest-southeast direction. A five-stage tectonic evolution of the Godavari basin is envisaged. Absence of volcanism, and the narrow rift zones, place the Godavari Graben in the 'Crevice' type of platform rift zone of Milonovsky (1972).
