Petrographic classification and Provenance study of Bhander Sandstones of the Vindhyan Supergroup, in the N-W Part of Bhopal, Madhya Pradesh, India

Abstract

Detailed field, petrographic and modal study of the sedimentary sequence of Bhander Group of the Vindhyan Supergroup explains that these sedimentary rocks deposited under shallow marine condition are the quartz arenites dominantly composed of quartz, presence of overgrowth and irregular and circlular inclusions in the quartz grains indicate the probably source of these sediments as falsic igneous rocks. The Modal analysis (QFL) data plotted on ternary plots also suggest the probable source of these rocks as craton anterior / continental block provenance.
