Abstract—The Upper Cretaceous rocks of the south east coast of the peninsula form one of the most
interesting formation of south India have been studied in detail by geologists. They are the relict
of the great marine transgression during the Cenomanian period. The cretaceous sediments of
Cauvery basin in south India have been studied and, the cretaceous foraminiferal research on
early in the exploration of hydrocarbons in the basin. The microfossils preserved in these outcrops
and three small inliers of these Cretaceous rocks occur among the younger Tertiary and post
Tertiary formations which cover the east coast of this great peninsular.
