Field and Petrographic studies on the Zaffergadh granitoids, Eastern Dharwar Craton, Southern India

  • Unique Paper ID: 182542
  • PageNo: 2443-2448
  • Abstract:
  • The Eastern Dharwar Craton (EDC) is composed of numerous granitoids from the Late Neoarchean to Paleoproterozoic eras, the origin of which remains uncertain. The Zaffergadh granitoids within the Eastern Dharwar Craton (EDC) are the subject of a petrological analysis in this study. The field observations, concise microscopic analyses of Zaffergadh granitoids, and exhaustive microstructural assessments demonstrate a substantial divergence from the igneous magmatic textures of origin to the modified microstructures. The Zaffergadh granitoids under investigation are identified by their distinct gneissic and colossal characteristics. The mineralogy of Zaffergadh granitoids is primarily composed of K-feldspar, plagioclase, and quartz, with significant amounts of mafic minerals, including biotite and amphibole. The orthoclase and albite minerals exhibit a distinctive perthitic texture. The study area has observed significant characteristics of the poikilitic nature of microcline and its replacement by plagioclase. The results suggest that the rocks have experienced metamorphism and deformation.
