Ongoing Mineral Exploration Programmes


CHINA-CLAY INVESTIGATION PROGRAMME
AROUND NAUDIHA-RAMGARH AREA,
DISTRICT SONBHADRA

                

GEOLOGY
 

The clay mineralisation of Naudiha-Ramgarh area lies in between latitude 24°25' : 24°28' and longitude 83°10':83°21' in survey of India toposheet No. 63P/7 and 63P/3. Clay is defined as the earthy hydrous alumino-silicate formed by decomposition of preferably feldspathic material, which does posses the property of plasticity when suitably tempered with water.

The clay occurrences are exposed near to surface with sandstone or beneath the topsoil and ferruginous sandstone, which are gently dipping in Naudiha Ramgarh area. The clay deposit occurs in sedimentary rock,which comprises of feldspathic sandstone. A sandstone outlier is seen all along the northern limit of Mahakoshal Group of rocks and contact with shale of Vindhyan Super Group in southern part.

The entire investigated area of clay has been divided into four blocks-

ACHIEVEMENTS

Investigation for clay deposit in Naudiha-Ramgarh and surrounding area is being carried out, where the reserves of clay deposit of about 16.5 million tonnes has been proved so far. The chemical analysis of the area revealed silica 59- 65%, Iron 1.2 5% and Alumina 17-26.41%). A thick clay zone of about 30-38 m in down-dip continuity has been encountered in Kuldiwa Kon Block and Bilwara-Sonjhar Block.
