molybdenum ore major

Skarn Deposits – Our Largest Source of Tungsten

The collection of ore minerals found in a skarn deposit depends mainly on the chemistry of the granite and are a mixture of sulphide and oxide minerals. Fe-skarns contain mostly the Fe-oxide mineral, magnetite. W-skarn contain mostly scheelite (tungsten ore), molybdenite (molybdenum ore) and the copper-iron sulphide, chalcopyrite.
