Cambay Shale Formation
Geologic formation in India
The Cambay Shale Formation is geologic formation in the Cambay Basin, India. It is of lower Eocene age. It varies in thickness from a few meters on the margins of the basin to more than 2,500m in the depressions. It directly overlies the Olpad Formation and is, in turn, overlain by the Anklesvar Formation in the southern part of the basin and by Kalol Formation in the northern part of the basin. Further north, the Cambay Shale, in its lower part, is gradually replaced by tongues of paralic-deltaic Kadi Formation and finally by Tharad Formation.
