Abstract

The work demonstrates the yield of field observation for identification of rocks, structural features, weathered and sheared zones. The hosted minerals in different rock types are identified due to the efficiency of light microscope to examine both mineral composition and texture. We argue in this paper that there is S-Z sheared zone along with major minerals of hornblende, pyroxenes, Biotite. The zone of mineralisation is found to possess ore mineral malachite, galena, chalcopyrite, haematite, molybdenite, anglesite and azurite. The area is subjected to the metamorphic agents of high temperature, pressure and chemicals that transform the pre-existing rock to metamorphic rocks while introducing new minerals of kaolinite, chlorite, actinolite and mica. The area hosting these minerals was mined since long time but it is currently a mined out area. It is evident that the thin section petrographically prepared can efficiently be used to mineral identification, texture and rock type.
