| Abstract | The central portion of the Rankin-Ennadai supracrustal belt contains a large number of mineral occurrences, including several major vein gold, polymetallic vein, and volcanic-associated massive sulphide
deposits.
Work to date indicates that most significant gold occurrences contain complex multistage, carbonate-bearing vein systems in which at least some gold-rich veins clearly predate regional deformation and metamorphism. Deformed, pyritic,
quartz-sericite schists of similar character to alteration zones in massive sulphide deposits are present in some gold occurrences.
Polymetallic vein occurrences contain high Au, Ag, Cu, and Zn, high Ag/Au ratios, locally anomalous Bi, Se, Te, As,
and Mo, and pyritic quartz-sericite schist. Both the veins and schistose alteration zones are deformed and metamorphosed
The critical features of polymetallic vein and some vein gold occurrences are similar to those of many porphyry and/or
epithermal deposits and suggest a major contribution to metal concentration by synvolcanic processes. |
