Abstract

The Tertiary rocks of the area between Narmada and Tapti rivers have undergone folding, faulting and partial erosion, whereas those of the adjoining area of Cambay basin to the north lie undisturbed,  technically, under the cover of Quaternary deposits. The exposed Tertiaries have been found to be folded into twelve linear anticlinal folds, plunging southwest and at times northeast as well, and invariably faulted along their southeast limbs. These faults are of reverse type and hade due northwest. The deformation was in all probability due to differential vertical basement fault-block movement caused by compressive forces related to the collision of the Indian Plate with the Asian Plate.
