按经济意义的相对顺序,太古宙贱金属矿床有下列类型: 1.层控和含有稀少脉状Fe-Ni-Cu硫化物,分布在诺尔斯曼—威卢纳绿岩带和福雷斯特(Forrestania)地区的变质富橄榄石超基性侵入岩体或岩流中。 2.层控Fe—Cu—Zn±Pb硫化物,分布在皮尔巴拉地块,诺尔斯曼—威卢纳绿岩带和伊尔冈地块西北部变质火山—沉积岩系中。 3.变质火山—沉积岩系中,除卡尔古利型金矿床外,还有广泛而呈小脉分布的Fe
In relative order of economic importance, Archean base metal deposits have the following types: 1. Stratigraphic controls and sparse Fe-Ni-Cu sulphides, distributed in the Nolsman-Wiluna Green Belt and Forrest Metamorphic olivine ultramafic intrusions in the Forrestania area. 2. Layer-controlled Fe-Cu-Zn ± Pb sulphides are distributed in the Pilbara massif, the Nolsman-Wiluna greenstone belt and the metamorphic volcano-sedimentary rocks in the northwestern part of the Ilgan block. 3. Metamorphic volcano - sedimentary rock series, in addition to the Kalgoorlie gold deposit, there are a wide range of small veins distribution of Fe
