Petrographic and Geochemical Characteristics of the Kanar Sandstone Formation, NE of Barwah, Khargone District, Madhya Pradesh

The study area located in Narmada valley region, NE of Barwah in the Khargone district, Madhya Pradesh, consists of several geological forrnations ranging in age from Archaean to Recent, including the Vindhyans. The Vindhyans are represented here mainly by the Kanar sandstone and Jamoti Shale which have been tentatively correlated with the Rewa Graup of Vindhyan Supergroup. The sandstone show primary sedimentary structures like current bedding, ripple marks, load casts, mudcracks, etc. Petrographic study reveals that the sandstones are quartz arenites of recycled orogcny. Thcsc rocks were most probably deposited in the shallow marine environment in a passive margin type. High concentration of trace elements like Co, Cr, Pb, Zn, Ni and Cu suggests their chemical affinity to iron, which is present as the principal cementing material in these rocks. The study further reveals that the granites and quartz monzonites were the principal source rocks and granodiorites to a lesser extent.
