Abstract

In the ARDAKAN BARITE ore deposits, two groups of copper ore minerals have been identified in the BARITE veins. The hypo gene ore minerals consist of chalcopyrite and chalcocite, which are associated with pyrite. The Super gene ore minerals are mainly composed of secondary Cu-sulfides (such as covellite, yarrowite and anilite), Cu-carbonates (malachite and azurite) and Cu-oxides (cup rite). Chalcopyrite is the most important hypo gene Cumineral which has been altered to Cu-super gene minerals. Chalcopyrite tarnishing were developed along the joints, fractures and grain boundaries as films and veinlets. The tarnish color on the chalcopyrite varies from deep blue, pale blue, pink, yellow and dark gray. The tarnish phases in the chalcopyrite were studied using SEM - EDXA. Sequences of the CHALCOPYRITE ALTERATIONs by the continued oxidation are as following: chalcopyrite (CuFeS2), covellite (CuS), yarrowite (CU9S8),spionkopite (CU39S28),geerite (Cu l.6S) and anilite (Cu 1.75S).Alteration and oxidation caused a series of changes from chalcopyrite to anilite. These changes include general fluctuations in the Cu/Fe and Cu/S ratio, so that some new minerals form by Fe and S depletion and Cu enrichment. Weathering of chalcopyrite to covellite results in a decrease in iron content with simultaneous increase in copper. Subsequent weathering of covellite to anilite caused an increase in the Cu/S ratio from 0.9 in covellite, to 1.12 in yarrowite, 1.45 in spionkopite, 1.64 in geerite, and to 1.77 in anilite. Super gene weathering in the chalcopyrite of the Arakan BARITE is mainly due to GALVANIC REACTIONS.
