Abstract: About 140 granitoids were studied magnetically and microscopically in the southern half of the Malay Peninsula (ca. N2°-N10°). The late Paleozoic to early Mesozoic granitoids of the Main Range of belt Malaysia and its northern extension to southern Thailand, and also the Eastern belt of Malaysia, are mainly composed of the ilmenite-series (91%). But small plutons of the Central intrusive belt and Cretaceous granitoids are of the magnetite-series in general. Tin deposits are distributed in the ilmenite-series granitic terranes. Thus genetic relationship between the reduced species granitic magma and tin mineralization is suggested.
