New Data on the Mineralogy of Chromite from the Nuggihalli Schist Belt, Western Dharwar Craton, Karnataka, India: Petrogenetic Implications
The occurrence of rhythmic layering of chromite and host serpentinites in the deformed layered igneous complexes has been noticed in the Nuggihalli schist belt (NSB) in the western Dharwar craton, Karnataka, South India. For this study, the chromitite rock samples were collected from Jambur, Tagadur, Bhakatarhalli, Ranganbetta and Byrapur in the NSB. Petrography and ore microscopic studies on c...
متن کاملInfrared Spectroscopic studies on the Mobility of Metamorphic Fluid in Quartz veins of Dharwar Craton
The thermal induced variations of water inclusions in their OH stretching mode region were probed in quartz veins from Dharwar Craton, India, using fourier transformed infrared spectroscopy (FTIR) in the temperature range 25 to 300 oC. All the inclusions have composition H2O-NaCl-CO2. The peak positions monotonously shift to higher wavenumbers with increasing temperature with slopes of 0.23 and...
متن کاملProvenance and Tectonic Setting of Late Archaean Greywackes from Dharwar Craton: Karnataka, India
Geochemical characteristics of greywacke and intercalated phyllites from Haveri and Dharwad block (long N 75° 10' to 75° 25' E and lat 15° 30' to 45° 00'S and (long 75° 05'E and lat S 15° 15' to 15° 35') of Shimoga basin have been studied to unravel the provenance and the tectonic setting of the greywackes. The greywackes are medium grained feldspatholithic and show presence of perthitic feldsp...
متن کاملInvestigation of mineralization, REE geochemistry, and fluid inclusions studies of the Shalang vein-type polymetallic ore deposit, southwest of Kerman
The Shalang vein-type polymetallic ore deposit is located about 10 km southwest of Kerman and 70 km northeast of Sirjan, and lies in the central part of the Dehaj-Sarduieh metallogenic belt. This deposit is hosted by dacitic and andesitic vitric and crystal tuffs along with andesitic-dacitic lava flows of Eocene age. The alteration zones related to this deposit are propylitic, intermediate argi...
متن کاملInvestigation of genesis and fluid origin in Noghduz gold bearing quartz veins, East Azarbaijan Province, northwest of Iran
The Noghduz prospecting area, as a part of the Arasbaran metallogenic zone is located about 20 km east of Ahar, East-Azarbaijan Province. The mineralization host rocks are andesite-trachy andesite with the age of Late Eocene. The hydrothermal alterations exposed in this area are silicic, argillic, and propylitic. Pyrite is the main hypogene sulfide mineral which is accompanied by lesser amou...
