| 中文摘要: |
| 中塔吉克斯坦贵金属矿床的产出大多与区域发育的古生代浅变质沉积岩系有关,矿化富集多见于不同岩性的层间裂隙、层间滑动带及层间破碎带等部位,具有较明显的层控性。本文所述金矿床位于中亚金属成矿域的中塔吉克斯坦贵金属成矿带中,从矿床成矿控矿地质条件和地球物理特征来看,矿体与酸性花岗质脉岩密切伴生,矿床的成因是与晚古生代黑色岩系沉积变形、变质及热液萃取改造作用有关,含碳浅变质碎屑岩带,尤其是碳质-粘土片岩层金的含量相对较高,为含碳浅变质碎屑岩型金矿床。矿床激电异常特征显示,高极化率、相对低电阻的物探异常是金矿化蚀边带的反应,该套组合异常往往是该区寻找金矿或相关的地质体的重要地球物理标志。 |
