Interpretation <strong>of</strong> these data in terms <strong>of</strong> sequence stratigraphy<br />
and polaeoenvironment.<br />
A reconnoitre survey <strong>of</strong> the exposures <strong>of</strong> Indravati Group around Jagdalpur has<br />
been completed. Stromatolites arc noticed only in Jagdalpur Limestone and Sbale Formation<br />
and arc present in the forms <strong>of</strong> carbonate build ups. Kanker Limestone Formation<br />
shows the presence <strong>of</strong> pyrite and carbonaceous nodules.<br />

Ihe Halkal Formation, Bhima Group, Karnataka were studied. These beds were equated<br />
wilh Precambrian-Camhrian transition. The detailed study <strong>of</strong> carbonaceous macr<strong>of</strong>ossil<br />
remains and associated organic-walled micr<strong>of</strong>ossils inelicate that tbe heels <strong>of</strong> Halkal Formation<br />
are oleler than Pre Varanger glaciation, i.e., 700 Ma. The biological remains compare<br />
with the worlel wide assemblages found lor the perioel 1000-900 Ma.<br />
