Geochemical-and Isotopic Studies of the Granitoids Exposed on the Southern Slope in the Sasoma-Saser Brangra Section of Karakoram Batholith, Jammu and Kashmir
Subscribe/Renew Journal
The Karakorarn Batholith is one of the geological features that traverses the entire Karakorarn range. There is wide compositional variation across the batholith. The granitoids of Karakoram Batholith separate the metamorphic complex from the Karakoram Tethys sequence. The purpose of this study is to provide geological information on the Karakoram batholith and to suggest possible mechanisms that were responsible for the development of granitoids of the southern slope of the Karakorarn Batholith between Sasoma-Saser Brangra regions. The studies suggest that, the granitoids are metaluminous to peraluminous (mol. A/CNK value is -1.0), have Sti, ratio ∼0.709, show volcanicarc affinity, and suggest emplacement age of ∼124 Ma. They represent the reworking of lower crustal Calc-Alkaline parental rocks.
