| 摘 要： | 四川底苏铅锌矿床是一个典型的沉积改造型矿床。改造热液中的铅锌来源于早阶段热水沉积矿石及地层岩石；矿化剂硫源自赋矿地层；介质水属于下渗大气降水。改造热液中的铅锌主要以氯、氟配合物形成迁移。在构造减压带中，铅锌配合物交代地层中的黄铁矿或被有机质还原而沉淀富集。

| Abstract: | Disu Pb-Zn deposit, Sichuan is a typical sedimentary-reworked one. Pb and Zn in hydrothermal fluid were derived from host strata and pre-existing sedimentary Pb-Zn ore. Mineralizer was of host strata origin. Water of hydrothermal fluid was derived from meteoric water. Metals were transported mainly as chloride complexes such as PbCl20 and ZnCl20. When metal-bearing solution moved along deep faults to cavities or frac tures, the metal cations reated with pyrite and organic matter and precipitated as sulfides. |
