| 中文摘要: |
| 山西东北部是贵金属(金、银)矿床成矿有利地区,是四个地体的拼合处。加上扳块的俯冲对金、银矿床的富集极为有利,具有较好的成矿远景。 |
| 英文摘要: |
| Gold and silver deposits in northeastern Shanxi Province occur in the amalgamation zone of four terranes at the north edge of the North China-Korea plate. The area which contuins these deposits has a triangle shape and is hence called“Gold Triangle”. Gold and silver mineralizations are controlled by the Yanshanian or Hercynian volcanic structures located at the intersections of the NE-, NW-and EWtrending faults which run in parallel to the boundary faults of the terranes, As a result of A-type subduction,the downgoing plates or slabs reached the mantle and generated the syntexis-type granites and gold and silver deposits. |
