Mineralogy and Element Variations in the Vindhyan Stromatolites, Central India

Abstract

The Lower Vindhyan stromatolites are dominantly made up of dolomite while the Upper Vindhyan stromatolites are made up of calcite. Sr shows sympathetic relationship with CaO and K₂O with Al₂O₃. Three distinct assemblages of stromatolites belonging to the Kajrahat Limestone, the Fawn Limestone and the Bhander Formation show different trace element distribution.
