| Abstract: | Most of the Proterozoic carbonate formations of Peninsular India, and the so-called ‘unfossiliferous’ carbonates of the Sub- and Lesser Himalaya, contain abundant columnar and branching stromatolites. Systematic study of some of these stromatolites supports their use in biostratigraphy and reveals their Riphean—Proterozoic affinity. A synthesis of stromatolite studies in India has been attempted. A biostratigraphic correlation of the stromatolitic formations of Sub- and Lesser Himalaya extending from Jammu in the west to Buxa in the eastern Himalaya has been established. A probable correlation of those of Peninsular India has been indicated, based on available information. A bibliography on Indian stromatolites is appended. |
