| 摘 要： | 佛子冲、东桃等热水沉积矿床中矿物流体包裹体分析表明 :铅、锌在成矿热液中迁移的主要方式为氯阴离子络合物 ,当热液进入海底后 ,由于海水的混入导致热液温度降低和 p H值升高 ,热液中 S2 -将会增加 ,铅、锌的卤化物络合物则变得不稳定 ,利于 Pb S和 Zn S的生成

| Abstract: | The analysis of fluid inclusion in minerals of hydrothermal depositional deposits such as Fuzichong,Dongtao deposit etc.show that anion chlorine complex was the main form for Lead and Zinc transportation in ore forming hydrothermal fluid.As soon as the fluid entered the sea floor,Lead and Zinc sulfides precipitated due to the decrease of the fluid temperature,ascent of pH and increase of reduced sulphur and unsteadiness of the Lead nd Zinc halide complex caused by seawater mixing. |
