| 摘 要： | 易门狮子山铜矿床位于昆阳裂谷易门裂陷盆地内,属沉积-改造型中型铜矿床。矿体主要赋存于落雪组白云岩中,并严格受狮子山背斜及北东向压扭性断裂控制。应用构造地球化学方法,重点研究了断裂构造岩微量元素分布特征及其异常分带规律,结果表明:断裂破碎带矿化蚀变强烈,构造岩中Cu、Bi、Mo、Co、Mn、Ag、Pb等成矿元素富集;矿床具有自上而下的轴向分带序列Ba-Mn-Ag-Zn-Cu-Pb-Co-Bi-Mo;横向上Cu-Bi-Mo-Co-Mn为矿体的近矿指示元素,Ag-Pb为远程指示元素;纵向上从矿床东部至西部,矿化强度及异常规模明显减弱,反映了该类型矿床分带明显的特征。根据地球化学找矿标志,3～8号勘探线间近矿晕规模大,是深部隐伏矿的主要靶区。

| Abstract: | The Shizishan copper deposit located inside the Yimen rift basin of Kuanyang Rift is a medium sized sedimentary-reformation type copper deposit. The main ore-bodies are hosted in the Luoxue Formation dolostone and constrained by the Shizishan anticline and NE-trending compresso-shear faults. Tectonogeochemical investigation shows that the fault zone is intensively mineralized,and the ore metals such as Cu,Bi,Mo,Co,Mn,Ag,Pb are especially enriched in the tectonites. The deposit is strongly zoned,axial zonati... |
