The area under investigation is exclusively metamorphic terrain. Main rock types exposed in the area are schist, phyllite, Quartzite’s, Sillimanite, Pyrophyllite, Corundum. Theserock types belong to Sakoli Group. The ore body trends NNE - SSW and has steep dip varying from 600 to 700 towards West. Corundum is sporadically associated with sillimanite and the both are encased with Pyrophyllite in the form of isolated lensoid bodies.

Petrological studies of the different litho units reveal that area under investigation comprising mainly, Corundum, Sillimanite schist, Pyrophyllite schist, Quartzite-tourmaline schist.Major oxide chemistry of the host rocks highlighted that concentration of alumina increases with decreasing behavior of silica which ranges from approximately 20% - 80%. The area whereas silica 2% - 80%. Nearly all the litho-units in the area shows high concentration of alumina and silica which ranges from 16.20% -92.16 % and silica ranges from 1.93% to 76.0%. These are showing negative trend in sillimanite schist. The bivarient plot of SiO2 versus K2O for Pyrophyllite schist indicates negative correlation which
concludes that alteration effect. Approximate content in the Sillimanite, Pyrophyllite schist and corundum is 0.6%, 0.35% and 0.24% respectively. The area is highly metamorphosed and slightly tectonically disturbed.
