| 摘 要： | 块状硫化物矿床可分为ＶＭＳ和ＳＥＤＥＸ矿床两大类。文章从赋矿岩石、成矿时代、控矿构造背景、矿石组分、矿化与蚀变等方面总结了两大类矿床的主要地质特征，从成矿流体性质、微量元素、硫同位素和铅同位素等方面总结了两类矿床流体成矿系统主要地球化学特征，论述了块状硫化物矿床的形成机理。

| Abstract: | The massive sulfide deposits are divided into two types: the volcanic hosted massive sulfide deposits (VMS) and the sedimentary hosted deposits of exhalation (SEDEX). General geological and geochemical characteristics of VMS and SEDEX are discussed in terms of the host rocks, the formation time and tectonic settings, mineralization and alterations and the composition of ore forming fluid system, trace elements and the S, Pb isotopes , and the ore forming mechanisms of the VMS and SEDEX are stated in this paper. |
