Abstract. The Chandi
limestone Formation of Raipur Group. Chhatt1sgarh Supergroup is divided
into three lithofacies designated as A. B and C in
stratigraphic order. Limestone samples from each lithofacies were analysed for mineralogical and geochemical characters. In X-ray Diffractograms. only calcite, dolomite and quartz are detected. Dolomite snows maximum development in lithofacies B. In the geochemical
results Cao shows
positive correlation vv;th Sr. Pb'. Zn. Cu. Ni in Lithofacies A indicating association vv;th calcite Mn and
insoluble residue shows positive correlation vv;th MgO in lithoqacies B. v..tiich suggests that higher Mn rs related
to
dolornitization. Similarly higher Na/Ca ratio in dolomite
suggests saline dolomitizing solutions. The trace elemental concentrations in general indicate normal
shallow
marine
environment of deposition.
