Abstract

Silicified cyanobacterial remains are recorded from the black cherts interbedded in the Donimalai Formation of the Archaean Sandur Schist Belt and amorphous organic matter in the stromatolites underlying Deogiri Formation of the same belt. The presence of elemental carbon at the fringes of the cyanobacteria is confirmed by microprobe analysis. Carbon (δ¹³C= -1.4 ± 0.5% vs PDB) and oxygen (δ¹⁸O= + 10.6±0.5% vs SMOW) isotopic ratios and the presence of cyanobacteria extend the existence of photosynthetic activity into the Archaean.

Abstract

A microbialite morphospecies Stratifera undata has been recorded in the Blaini Formation of Mussoorie Syncline and is systematically described. It is inferred that this mat complex was deposited in an upper intertidal region in subtropical climate. The age of this microbialite morphospecies is suggested to be Upper Riphean/Lower Vendian.

Keywords

Abstract

A manganiferous horizon was recorded near Niralkeri, in an intricately folded quartzite-chert breccia-mudstone sequence of the Simikeri Subgroup in the Kaladgi Basin of Karnataka. The nodules collected from this horizon show the presence of todorokite, vemadite and lithophorite in association with quartz and hematite; with MnO-58%.

Keywords
