块状硫化物矿床主要有两种类型 :火山岩容矿型 (如日本黑矿 )和沉积岩容矿型 (如加拿大苏利文矿床 )。近年来 ,在西班牙和葡萄牙的伊比利亚区发现了一条长 2 50 km,宽 2 5~ 70 km的黄铁矿带 ,其中产有若干世界级的超大型锡多金属块状硫化物矿床。根据对这些矿床的地质特征、成矿流体包裹体、H、O、S、Pb同位素及成矿环境和成矿模式的研究表明 ,它们具有明显不同于火山岩容矿型或沉积岩容矿型块状硫化物矿床的特征 ,而是一种新类型的块状硫化物矿床 ,称之为伊比利亚型。文章介绍了该矿床地质地球化学研究的最新进展情况
There are two main types of massive sulfide deposits: volcanic-hosted (eg, Japanese black) and sedimentary-hosted (eg, Sullivan, Canada) deposits. In recent years, a pyrite belt measuring 250 km long and 25 to 70 km wide has been discovered in the Iberia area of Spain and Portugal. There are several world-class ultra-large tin polymetallic massive sulphide deposits. According to the geological characteristics of these deposits, the study of ore-forming fluid inclusions, H, O, S, Pb isotopes and metallogenic environment and metallogenic model shows that they have obviously different characteristics from volcanic ore-hosted or sedimentary-hosted ore- Sulphide deposits, but a new type of massive sulphide deposit called the Iberian type. The article introduces the latest progress of geology and geochemistry of this deposit
