| 摘要: |
| 饶家山地区紧邻金溪县城以东,二十世纪70年代初,有关单位在该区开展过大量的地质找矿及科研工作,并未发现成型的工业矿体,但积累了大量地质成果。近两年通过对资料的二次开发、验证,在该区发现有较好的银铅锌矿化。笔者在总结前人成果资料的基础上,从成矿地质背景、矿化特征入手,结合堆积始于唐朝的大量古炉渣分析,表明本区具备形成大型银多金属矿的成矿条件,具有较大的找矿远景。 |

| Abstract: |
| The Raojiashan region is located in the middle part of the Wuyishan precious polymetallic mineralization zone,and characterized by well-developed fault structures,intense magmatism,well-defined geochemical anomaly and pervasive silver polymetallic mineralization,and numerous ancient galleries and significant quantities of ancient slag deposits.The copper and molybdenum mineralization appears mostly in and near the massifs and dikes in the Lengshuikeng region,where the widespread alteration and mineralization indicate the possibility of larger-scale orebodies in the deep levels.The NW-trending faults occur as major ore-control structures,and the Yanshanian magmatism once played an important role in the polymetallic mineralization in the study area.The ore shoots tend to be concentrated in granite porphyry or neighbouring fracture zones.The mining remains of numerous ancient galleries and significant quantities of ancient slag deposits may also be the evidence on exploration potential in the study area. |
