Ore and gangue mineralogy and zonation The dominant sulfide mineral in most VMS deposits is pyrite, but pyrrhotite is dominant in others. Marcasite, which is present either intergrown with fine grained pyrite or as a replacement product of pyrrhotite, is generally a minor

The mining industry of Cyprus was active in the production of minerals of copper, iron pyrite, gold, chromites as well as asbestos fibers. Since 1979 the mining industry of Cyprus is in recession because of the exhaustion of the known large and rich copper and iron pyrite ore bodies and the increase of the production cost without proportional increase in the international sale prices of metals.

Typical Cyprus-type deposits comprise massive brecciated pyrite ores, underlain by a vertically extensive quartz-pyrite-chlorite stockwork. Sandy pyrite or conglomeratic ore, similar to that found in the TAG mound, is characteristic of the upper parts of Cyprus-type deposits.

Chalcopyrite as a principal ore of copper is much more useful. Pyrite is paler yellow, chalcopyrite has more intense color. Width of sample 8 cm. Hannukainen, Finland. Large boulder of massive sulfide from Cyprus. It is called massive because it is indeed full of pyrite and contains little else. Here is an example of pyrite as a rock type.
