Such minerals may contain high concentrations of lead, zinc, and copper, usually in sulfide minerals like galena (lead sulfide), sphalerite (zinc sulfide), and chalcopyrite (copperiron sulfide). Since they are included within the sedimentary strata they are called stratabound mineral deposits.
Africa's significance as an iron ore producer is, of course, reduced by the fact of these widely dispersed resources. In 1974, on the eve of the world crisis, Africa's share (excluding South Africa) of world mineral output was % for iron ore, 17% for copper, 10% for bauxite .
Skarn ore minerals. 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. Feskarns contain mostly the Feoxide mineral, magnetite. Wskarn contain mostly scheelite (tungsten ore), molybdenite (molybdenum ore) and the copperiron sulphide,...
