The interesting aspect of Indian granite quarries is that they are located in areas nearby ports and stone processing factories. It makes things happen in favor of both granite buyers and suppliers. With ports like Kandla, …
The gneissic granites from different plutons show various mineral assemblages of biotite + plagioclase + K-feldspar + quartz ± muscovite ± garnet ± amphibole ± epidote-zoisite ± allanite ( Table 2 ), suggesting a range of protolith compositions and different degrees of metamorphism from greenschist- to granulite facies.
Commercial Granites from Rajasthan KEYWORDS Commercial Granite, Mining, Mineral Economics ORIGINAL RESEARCH PAPER INTRODUCTION Granite is considered as a valuable mineral resource and comes under the category of dimensional and decorative stone. Technically granite refers to a light-coloured granulose plutonic rock composed

Abstract This study deals with natural radioactivity levels of the ten most important commercial granites from various districts currently being exploited as dimension stone in Turkey. Determining the level of radioactivity is important for human health, particularly for indoor use of granites. This study shows that the relationship between the natural radioactivity and the radiogenic ...
on this basis, he referred to three types of granite: (1) epizonal granites—discordant plutons crystallized from magma with only minor evidence of granitization; (2) mesozonal granites—plutons that are in part discordant and …
The Quaternary sediments on granite are a set of Marine and continental deposits with a thickness of 20 m–30 m. There are several granite rock masses, such as Zhangzhou granite, Chengxi granite and Maping granite, which are around Zhangzhou geothermal field (Yang, 2016).
