Coal also occurred as cyclic succession of coal, shaly coal, carb shale, grey shale & sandstone. Altogether 14 coal seams were encountered. Resources were not estimated during the year. Coal seams occurred with Barakar formation as cyclic succession of shale, carb shale, shaly coal, coal & sandstone. 15 coal horizons have been intersected in this area. During the year about 29 million tonnes of C to G grade coal resources were estimated. Main litho units are shale, limestone & laterite. Limestone is mostly horizontally bedded, trending E-SW. Depth of the limestone was confined upto 33 m. Limestone of this area is grey to pink, hard, compact, massive and stromatolitic. About 80 million tones limestone resources were estimated so far out of which, 50 million tonnes of cement (blendable)/ beneficiable) grade limestone resources were estimated during the year. Limestone of the area belongs to Jagadalpur & Kanker formation of Indravati Group. Limestone occurred as small mounds & is horizontally bedded with local warping. Outcrops of limestone were found in an area of 0.90 x 0.30 km with a thickness upto 10 m. Deposits of high grade limestone were demarcated around Villages Chitapur and Devrapal. So far, 13 million tonnes of cement grade limestone resources were estimated, out of which about 6.70 million tonnes of cement grade limestone resources were estimated during the year. Area is mostly covered with Dongargarh granite with numerous acid & basic intrusive. Granite block (dolerite) has been marked as hillocks with dimesnsion of 500 m x 150 m. Thickness was found to be around 10 m. These rock are suitable for cutting/polishing purpose. About 75,000 m (Contd.) 3 granite block (dolerite) resources were estimated.

During the current year, no production of quartzite and steatite was reported from the state while all other minerals produced in the state reported higher production as compared to previous year (Table - 4). The value of minor mineral production was estimated at ` 280 crore for the year 2010-11. The number of reporting mines in Chhattisgarh was 153 in 2010-11 as against 152 in the previous year.
