| 中文摘要: |
| 白云金矿是辽宁省东部大型金矿床之一,矿区内岩脉发育,与成矿作用密切相关。结合对野外地表、坑道和钻孔的详细观察,初步理清各岩脉之间侵位先后顺序为辉长岩SymbolnB@花岗斑岩SymbolnB@石英斑岩SymbolnB@(矿体)SymbolnB@闪长玢岩SymbolnB@煌斑岩。利用岩脉探讨了区域构造特征,并结合岩脉本身的矿化信息探讨了岩脉与成矿关系。 |
| 英文摘要: |
| The Baiyun gold deposit is one of the major gold deposits in eastern Liaoning Province. Various dikes widely outcropped in the gold deposit area,which are closely related to gold mineralization. In combination of field observation, trenching and drilling data, the emplacement order among dikes was studied. The results showed that the gabbro dike significantly formed earlier than other veins, and the granite porphyry earlier than the quartz porphyry, and followed by the diorite, and the lamprophyre emplaced finally. Furthermore, the regional tectonic features and the relationship between dikes and gold mineralization were discussed based on the characteristics of these dikes such as gold mineralization within dikes.. |
