摘要: Iron oxide-copper-gold(IOCG) minera-lization occurs within and peripheral to a large-scale Proterozoic breccia system known as Wernecke Breccia. The related minera lization appear have formed, independent of magmatic cycle, during the expansion over-pressured, hot, highly saline, basinal fluids into weak and/or permeable regions strata temporal evolution Basin. mineralization contains abundant magnetite hematite is similar typical IOCG deposits. However, formation Breccia in thick evaporite-bearing sedimentary package also has similarities sediment-hosted copper deposits such those Mount Isa area Zambian belt.
