引言本文主要评述元古宙与火山岩伴生的喷气块状硫化物矿床类型及其地质环境。层控喷气块状硫化物矿床在全世界元古宙地体中都有分布。这些矿床是铜、锌、铅、银、金、镉和锡的重要来源。有几个元古宙含镍块状硫化物矿床可能是属于这种矿床类型。用来说明这种矿床类型的例子有北美、澳大利亚、南非、斯堪的纳维亚和芬兰的矿床。但这种类型的矿床已知在某些其它元古宙地体中也有分布,例如苏联和印度的矿床。元古宙喷气块状硫化物矿床的金属比例是从富铜和贫铅及锌变到富铅及锌和贫铜。
Introduction This paper mainly reviews the types of jet-laden sulfide deposits associated with volcanic rocks in the Proterozoic and their geological environment. Stratigraphic-controlled jet massive sulphide deposits are distributed throughout the Proterozoic terrestrial world. These deposits are an important source of copper, zinc, lead, silver, gold, cadmium and tin. There are several Proterozoic nickel-bearing massive sulfide deposits probably belonging to this deposit type. Examples of the type of deposit used to illustrate this type of deposit are in North America, Australia, South Africa, Scandinavia and Finland. However, this type of deposit is known to be also distributed in some other Proterozoic terranes, such as the deposits of the Soviet Union and India. The metal ratio of the Proterozoic gas-jet massive sulphide deposits varies from copper-rich and lean to zinc-rich to zinc-rich and copper-poor.
