Primary tin mineralization in Peninsular Malaysia can be grouped into four broad classes: (i) pneumatolytic-hydrothermal lodes, veins, stockworks and stringers, (ii) pyrometasomatic skarns which can be subdivided into stanniferous and stanniferous-iron varieties, (iii) tin-bearing pegmatites and aplites, and (iv) stanniferous polymetallic sulphide bodies.
