澳大利亚Cloncurry地区大部分被元古宙地层所覆盖,其中赋存有大量世界级的成矿热液系统。大型热液系统大都与含磁铁矿或赤铁矿等铁氧化物的铁矿化岩石密切相关。铁氧化物和铜金矿化的矿物学、地球化学及年代学特征反映出成矿过程可能涉及到多种流体间的作用和水岩反应。对Cloncurry地区典型矿床和区域Na-Ca热液系统的研究表明,含铁氧化物的铁矿化岩石与铜金矿化之间的关系可分为4类:①贫磁铁矿或赤铁矿的"Kiruna-型"铁矿化岩石;②铜金矿化赋存于含铁氧化物的铁矿化岩石中;③与铁氧化物有关的铜金矿化;④少量或者不含铁氧化物的铜金矿化。该分类提供了一些与铁氧化物有关的铜金矿化成因联系、矿物...

Cloncurry district is underlain by Proterozoic rocks in which many world-scale hydrothermal systems occur. The large hydrothermal systerms are closely associated with magnetite or hematite-bearing ironstone. Mineralogy, geochemistry and choronology of oxidation of iron and Cu, Au mineralization indi- cate that interaction of several fluids and different water/rock reractions during formation of the ores. Study on Na-Ca system of typical ore deposits and areas in Cloncurry district shows that relation of iron oxide-mineralized rock to Cu-Au mine...
