ABSTRACT:
On the basis of lithological characters, Chandi limestone formation of Raipur group is divided into three lithofacies A, Band C, represented by stromatolitic limestone, dolomitic limestone and cal-careous shale respectively. X-ray diffraction data reveal predominance of calcite in lithofacies A and of dolomite in lithofacies B, followed by occurrence of quartz. Petrographic studies suggest penecontemporaneous dolomitization for dolomites of lithofacies B. Higher Mg/Ca ratio in lithofacies B as compared to A and C, conforms to XRD results and accounts for dolomitization effect in the former. Similarly low Sr, Pb, Zn, Cu, Ni, and high Mn content in dolomitic limestone of lithofacies B in comparison to limestones of lithofacies A and c is related to the replacement origin of dolomites. Presence of stromatolite, desiccation crack and intraformational conglomerate structures associated with Chandi limestone are suggestive of upper intertidal to supratidal environment of deposition. Most probably evaporative conditions resulted in an increase of Mg/Ca ratio to a value that permitted replacement of calcite by dolomite.
