摘要
会泽铅锌矿床成矿作用受构造控制明显,主要与压扭性断裂作用有关。H,O,C,S,Pb同位素和包裹体资料、断裂构造地球化学和矿床地球化学分析表明,矿床形成于持续开放体系条件,并且持续开放体系下的(断裂)构造作用控制了矿床成矿元素的活化迁移与含矿流体的形成、流体的迁移汇聚及矿液的沉淀与矿床的定位。持续开放体系下的构造(断裂)作用对矿床的形成起了决定性作用。
Structural geology, mainly related to compression-shear faulting, was supposed to have been the major control over the regional metallogenesis of the Huize Pb-Zn deposit. The continual open system under which the deposit formed was well recognized in the light of studies of Pb and stable isotopes (H, O, C and S), fracturing and Pb-Zn mineralizing geochemistry. In essence, the fault system developed under the continual open system was the key to the activation and transportation of ore-forming elements, the formation and advection of ore fluids, and the emplacement of ore bodies. It is thus a crucial geological process for the formation of the Huize Pb-Zn deposit.
