Genetic Issues of Some of the Non Metallic Minerals in Lesser Himalaya
A brief account of the representative and workable industrial minerals namely magnesite, talc and barite in Lesser Himalaya, is presented here emphasizing their genesis. Deposits of magnesite and talc are found associated with Neoproterozoic, plateform type, shelf-slope limestone-dolomite host rocks from inner Lesser Himalayan sequences. Field, textural, geochemical signatures and fluid inclusi...

متن کاملfactors affecting the productivity of non-metallic minerals industry during the third plan
although economic and managerial literature is replete with studies that probe about productivity but only a few studies decompose it to its components (technological changes, managerial efficiency changes and scale efficiency changes)and analysis their share in productivity changes (positively or negatively). accordingly, this article attempts to explain the issue by decompose productivity to ...
متن کاملA Study on Integrating Geology Data, Surveying Data, Minerals Data and Establishing Visualization Application Systems
This paper proposes an architecture for integrating geology data, surveying data, minerals original data and establishing visualization application systems in mine. In this architecture, geology data, surveying data and minerals data are classified and integrated in the original database. The original database and corresponding database management system (DBMS) can provide a common and standard...
