Platinum and palladium are precious metals generally found in ultramafic rocks The source of platinum and palladium deposits is ultramafic rocks which have enough sulfur to form a sulfide mineral while the magma is Atype granitoids are ferroan alkali–calcic, although some are ferroan alkalic Most are metaluminous although some are peraluminous Caledonian post A Geochemical Classification for Granitic Rocks Oxford
