Infrared 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 کاملNew 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 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 کاملLithospheric structure of the Pilbara Craton, Capricorn Orogen and northern Yilgarn Craton, Western Australia, from teleseismic receiver functions
The upper lithospheric structure from the Pilbara Craton, across the Capricorn Orogen, to the northern Yilgarn Craton is determined from high-fidelity broadband seismic data. Three-component temporary stations were deployed in a line running southwards from Marble Bar, Western Australia, at approximately 118 E longitude. They were in position between July and October 2000. Receiver functions ar...
متن کاملMetamorphism of basement rocks in the Central Zone of the North China Craton: implications for Paleoproterozoic tectonic evolution
Lithological, structural, metamorphic and geochronological data for the North China Craton enable its division into the Western and Eastern Blocks of Archean to Paleoproterozoic age separated by a north–south trending Paleoproterozoic orogenic belt: the Central Zone. The Central Zone is divisible into a series of lowto medium-grade granite–greenstone belts and high-grade metamorphic terrains co...
