Abstract/Notes | Abstract The Rewa Group of the Son Valley has been reclassified into five formations, i.e., Panna Shale, Asan Sandstone, Jhiri Shale, Drammondganj Sandstone and Govindgarh Sandstone in the ascending order. While two basal formations are developed only in the central and eastern part of the northern outcrop belt, the upper three are much more extensive than the underlying formations. Drammondganj Sandstone and Govindgarh Sandstone are newly defined formations, and the two constitute the 'Upper Rewa Sandstone' of earlier classifications. The scarp section at Drammondganj is the type area of the former, while the latter has its type area on the northern slope of the hills south of Govindgarh. Analysis of palaeocurrent in Drammondganj Sandstone, trend of thickness variation as well as of the regional stratigraphic relations collectively point to a northeasterly slope of the marine Rewa basin. The basin was replaced by a westerly sloping fluvial basin during the late phase of Rewa sedimentation. |
