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 کاملNeotectonic Evidences of Rejuvenation in KaurikChango Fault Zone, Northwestern Himalaya
Neotectonic investigations using morphotectonic parameters such as basin asymmetry, drainage anomalies, digital data interpretation and geomorphic field evidences were carried out in Satluj river valley downstream of Khab in the Kaurik Chango Fault (KCF) zone. The study reveals the presence of a north-south trending fault which is similar to the KCF. Unpaired, tilted terraces, V shaped valleys,...
متن کاملThermal metamorphism in the lesser Himalaya of Nepal determined from Raman spectroscopy of carbonaceous material
The determination of metamorphic conditions is critical to the understanding of the formation of mountain belts. However, all collisional mountain belts contain large volumes of accreted sediments generally lacking metamorphic index minerals and are therefore not amenable to conventional petrologic investigations. By contrast, these units are often rich in carbonaceous material, making it possi...
