Main Range Granites

The Main Range granites of Peninsular Malaysia form the backbone mountain ranges of the Peninsula, and represent the Centrel Granitoid Province of SE Asia. These granite bodies comprise a series of large mesozonal batholiths and plutons of biotite granites of S-type ilmenite series, emplaced into Lower to Middle Paleozoic-grade metamorphic rocks in Peninsular Malaysia. The genesis of the Main Range granites has been sugested to be in an A-type subduction setting and indicate of syn- to post-collisional. There are the granites which are associated with tin mineralization throughout the Peninsular Malaysia and as far south as the Indonesian island of Billiton.
