摘要：

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