| 摘 要： | 西藏工布江达县亚贵拉铅锌矿床位于狮泉河-纳木错-嘉黎结合带南侧,隆格尔-工布江达弧后断隆带内,矿体产于上石炭-下二叠统来姑组变石英砂岩与大理岩岩性转换部位,呈层状、似层状产出,其产状与地层一致。文章通过对矿床地质、地球化学特征和流体特征的研究,分析了矿床成因。矿区岩、矿石稀土元素地球化学特征及硫同位素分析表明,成矿物质主要来自深部物源区,氢、氧同位素资料证明成矿溶液为岩浆水和变质水组成的混合水,矿床既具有明显的热水沉积成因特征,又受后期岩浆热液的强烈叠加,属热水沉积-岩浆热液叠加改造型矿床。

| Abstract: | Yaguila lead-zinc deposit in the Gongbujiangda county of Tibet is located in the back-arc fault uplift area of Longgeer-Gongbujiangda of the south part of Shiquanhe-Namucuo-Jiali belt.The deposit is occurred in the lithology transformation of altered quartzose sandstone and marble of upper Carboniferous-lower Permian Laigu group.Orebodies,consistent occurrence with the strata,exists as layer and stratabound.The authors analyzed its genesis through an integrated study of geological characteristics,geochemist... |
