POHARA SILLIMANITE MINE (GARPENDARI HILL EAST)
Owner: Maharashtra State Mineral Corporation
MSMC’s Pohara Sillimanite Mine (Garpendri Hill East) in Bhandara District is also producing aluminous ores, namely Sillimanite, Quartzite and Pyrophyllite.
The details of mine are as under:
|Mineral||Sillimanite, Quartzite and Pyrophyllite|
|Nearest Rly. Station||Bhandara Road(40kms.from Mine)|
|Reserve||0.0375 Million Tonnes of Sillimanite|
|Total Lease hold Area||31.35 Hect.|
The area lies in toposheet No. 55 O/16 survey of India, at latitude North between 21°01’30″ to 21°02’55″ and longitude between 79°51’28″ and 79°51’45″ east and is situated about 800 M Due east of Pohara village.
Sillimanite is the main mineral occurring in the area. The ore-body exists in isolated patches lensoid shape, encased with pyrophyllite. Corundum is also associated with Sillimanite and the former is present within the Sillimanite ore-body in very small sporadic patches. Regionally the rock formation encountered in the area belongs to south-western part of the Sakoli synclinorium consisting of Sakoli series rocks of Archean group. The area is exposed in large triangular outcrop, and is also known as Bhandara triangle, the types representing Sakoli series are Phyllite quartz-muscovite-schist, quartz-chlorite-schist,quartzite,quartz-kyanite,sillimanite-pyrophyllite-schist,amphibolite-schist.
The geological sequence of the area is as follows:
|Recent||Soil and alluvium
|Post Sakoli||Pegmatite & Amphibolites
|Sakoli||Chlorite-Mica-Schist and quartzite
The ore-body trends NNE-SSW and has steep dip varying from 600 to 700 towards west. The rocks are highly jointed. Oblique- joints and bedding joints are prominently visible. Corundum is sporadically associated with Sillimanite and both the minerals are encased with Pyrophyllite in form of isolated lensoied bodies.
