Facies Development and Depositional Environment of the Mungra Sandstone, Kolhan Group, Eastern India

Preliminary study through process-Related facies analysis in late Paleoproterozoic-Early Mesoproterozoic Mungra Sandstone Formation of Kolhan Group, the least studied stratigraphy in Singhbhum Geology, reveals two major facies types, viz, hummocky sandstone bodies (below fair weather wave base) and planar and crossstratified sandstones (above fair weather wave base). From contact relations between facies types and facies succession development, a lower shoreface environment is inferred. An E-WW paleoshoreline orientation is suggested for the Mungra Sandstone Sea.
