SummaryThe Dalma volcanic belt in the Precambrian Eastern Indian shield is composed of a thick sequence of volcani-sedimentary assemblage with a group of predominantly ultramafic volcaniclastics having komatiitic chemistry. A volcanic origin is suggested by textural relationships and mineralogical composition, together with the presence of devitrified glass shards; these rocks are now mostly chlorite-tremolite schist.
