Abstract

Occurrence of sand filled ferruginised nodules from the shaly unit in the basal part of Gonvindgarh Sandstone of the Rewa Group of the Vindhyan Supergroup, is discussed. Randomly oriented within the host sediment, the nodules range in length from 2 cm to 25 cm. Width and thickness are variable within the nodule. Nodules show no relationship with the bedding of the host rock. Nodules are made up of quartz grains, micas and haematite. Poikilitic growth, due to precipitation of ferruginous material within cavities of the host sediment, is suggested as the possible mode of origin of the nodules.
