| 摘 要： | 脉岩与金矿床有着密切的成生关系。大新屯矿区闪长玢岩脉十分发育，闪长玢岩与金矿体赋存于同一构造控矿系统，二者沿NW向构造产出，空间上紧密相伴，时间上具近相同的成生关系。正确认识它们相互之间的关系，建立脉岩找矿标志，能有效提高找矿效果，减少生产和探矿过程中的盲目性。

| Abstract: | The dike rocks have close genetic relationship with the Au deposit. Veins of diorite porphyrite in Daxintun mining area are well developed, and both diorite porphyrite and gold ore-bodies occurred in the same ore control structure system, and the occurrence of them are along the NW strike structure while they are close to each other in space and have same genetic relation in respect of time. Correctly understanding their relationships and setting up dike rocks as clues for prospecting can improve the efficiency of prospecting and reduce blindness in the process of production and prospection. |
