| 摘 要： | 干河坝金矿床产于勉、略、康构造混杂岩带中。矿体受与近东西向区域主构造平行的次级构造-F3断裂及其旁侧剪切构造带控制,该构造既是导矿又是矿体最终就位的有利空间。赋矿岩石主要为乔子沟火山岩,经多期次构造挤压、剪切滑动,岩石普遍发生变形、蚀变,使本身金背景值较高的此类地层岩石成矿元素进一步活化、富集,再与导矿剪切构造复合叠加,最终富集成矿。

| Abstract: | Ganheba gold deposit originated from the tectonic mflange belt of Mian-Lue-Kang. The ore body was controlled by a secondary geologie strueture-F3 and its nearby shear tectonic belt, which is parallel to the main structure of NW. The structure-F3 is conducting ore, and is the most perfeet place for the ore body. The host rock is mainly volcanic rock of Qiaozigou, which had undergone several tectonic compressions, shearing and slides. Most rock had become deformed and altered but these created the conditions of gold minerogenetic elements activation and enrichment. It staeked with conduc- ting sheared structure and formed the mine finally. |
