摘要
湖南水口山矿田成矿作用受构造控制明显，主要与压剪性断裂作用有关。Ｈ、Ｏ、Ｃ、Ｓ、Ｐｂ同位素资料、断裂构造地球化学与矿床地球化学分析表明矿床形成于开放体系条件。开放体系下的（断裂）构造作用控制了矿田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，文中分析了其动力学机理。最后建立了矿田的开放体系构造成矿动力学综合数学模型，对成矿过程进行了计算机模拟。
The ore-forming processes are controlled obviously by tectonics and mainly related to compresso-shear faulting in Shuikoushan ore field, Hunan. Analyses of H,O,C,S,Pb isotope,fracture tectono-geochemistry and ore deposit geochemistry show that the ore deposit is formed in an open system. The tectonism(faulting)in the open system made ore-forming elernents activate,migrate and the ore fluid form,fluid flow ,and focuse,ore solution precipitate and ore deposit locate. The dynamic mechanism are discussed in the paper, Finally, the dynamic model of tectonic ore-forming in the open system is founded for ore field, and the ore-forming process is modeled by computer.
