Evidence of Volcanism and Glaciation from the Sausar Group, Central India

Palaeoproterozoic rocks of the Sausar Group, central India, are exposed on the southern flank of the Satpura Mountain Belt. Mapping in different parts of this belt indicates complex evolutionary history. The presence of a volcanosedimentary unit in the basal part of the Sausar Group is reported here. The sedimentological characters of the overlying unit indicate its glaciogenic origin. Association of volcanogenic and glaciogenic rocks in the Sausar Group could be used as tectonostratigraphic tool for supercontinent assembly during Palaeoproterozoic.
