Petrography and geochemistry of the Miocene Limestone of Saurashtra, Gujarat, West India

Petrographically, the carbonate rocks of Saurashtra are of four major types, viz. foraminiferal wackestone, molluscan wackestone, foraminiferal packstone and algal foraminiferal packstone. Geochemical and stable-isotope analysis of these rocks indicates low strontium, high manganese and depletion in...

Zusammenfassung:Petrographically, the carbonate rocks of Saurashtra are of four major types, viz. foraminiferal wackestone, molluscan wackestone, foraminiferal packstone and algal foraminiferal packstone. Geochemical and stable-isotope analysis of these rocks indicates low strontium, high manganese and depletion in δ18O. We suggest that these are the effect of diagenetrc alteration.
