【摘要】 西昆仑地区的成矿主要集中在奥依塔格—库尔良裂陷盆地的泥盆—石炭系沉积建造之内,野外考察和样品测试结果显示:该区铅锌矿化是由于各期构造运动期间(如海西运动、燕山运动以及喜马拉雅运动)热卤水的运移而形成,特别是喜马拉雅期大规模的逆冲推覆和褶皱作用的发生,导致了油田卤水和深层流体的混合,从而使得成矿物质不断沉淀而富集成矿。更多还原

【Abstract】 The Western Kunlun district mineralization is mainly located in a lower Carboniferous-Devonian system dolomitic limestone series on the top of the crack basement(Oytage-Kuerliang).Field and laboratory data from several ore deposits indicate that Pb-Zn mineralization took place in dolomitic limestone strata by ascending hot, saline fluids probably during every tectogenesis, such as Hercynian movement,Yanshan movement and Himalaya movement. The geochemistry of the ore fluid and the mineralization have shown that at the regional scale, the mixed features between oil field brine and deep-sourced brine caused metallogenetic matter enriching and precipitating especially during the Himalaya Period’s reversed napped fold process.更多还原
