Geology of the Punjab Salt Range

WITH reference to Sir Cyril Fox's interesting article under the above heading1, I wish to make certain comments. I think that nobody maintains that the Kohat-Potwar Saline Series is of post-Eocene age. As Prof. Sahni says2, his "fossil evidence is consistent with any geological age from the Lower Tertiary to the recent. But since on stratigraphical grounds the Saline Series cannot be younger than early Tertiary, the conclusion is that it is of Eocene age". I have shown3 that the latest marine beds of that region are of Upper Khirthar (Auversian) age; so there were apparently no marine waters to desiccate, in that region, after the Eocene.
