| 摘 要： | 甘肃省错沟—寺大隆铜(锌)成矿带位于奥陶纪弧后盆地和岛弧扩张脊火山岩带内,沿成矿带分布有5个矿化集中区,区内典型矿床研究表明:矿床形成于强烈拉张的构造背景,赋存在蛇绿岩套中—上部的基性火山熔岩—火山碎屑沉积岩中,受古火山机构和其原生构造裂隙控制,根据控矿条件分析,今后有必要对蛇绿岩套发育、存在以Cu为主的化探异常、海底热液喷流标志明显的摆浪沟地区和小砂石地区进行深入的找矿工作。

| Abstract: | Cuogou Sidalong Copper(zinc) metallogenic belt located in the spreading-ridge volcanic rocks belt of the Ordovician back-arc basin and the island-arc,there are five mineral areas in the belt,it is demonstrated by the studying on the typic deposits in the belt that deposits were formered in extended geologic setting and located in the middle-upper basic volcanic lava-volcanic clastic sedimentary rock of ophiolite suite,the orebody is controlled by paleovolcanic apparatus and it's original tectonic crack,on the analysis of the condition of ore-forming,the author deems that there is necessity to work on the Bailanggou area and Xiaosasi area,where Ophiolite suite is developed well and have Cu-chemical-prospecting anomalies and submarine hydrothermal-solution spouting sign. |
