Geochemistry and Petrological Studies of the Mesoproterozoic Glauconitic Sandstone, Semri Group, Vinration of K for the formation of glauconite. Al.O./TiO. ratio of glauconite rocks suggests its derivation from felsic source rocks. The ratio Al.O./SiO.?>?5 of glauconitic sandstone shows low to moderate maturity revealing the tectonic process during sedimentation. The tectonic discrimination diagra

The mafic volcanic rocks of this belt correspond to back arc regime with a MORB composition, whereas active continental margin is
