| 摘 要： | 通过对金华山矿区构造控矿规律研究，认为矿区矿脉主要受两条主干断裂之间的桥域控制,主断裂旁侧的引张区控矿，南西向侧伏的断裂构造控矿，北北东走向的断裂构造控矿。在成矿期，两条北东向主干断裂左行剪切，从而产生北北东向挤压和北西西向拉伸，使两主断裂面间所夹持的几组北北东走向的次级断裂张开成矿。 |

| Abstract: | Based on the investigation of structural ore-controlling regularity in Jinhuashan gold mining area, this paper proposes that the ore veins are controlled by the rock bridge between the two main faults, the ore body is controlled by extension region beside the main fault, the ore body is controlled by SW lateral trending fault structure and NNE trending fault structure. In the metallogenic period, the two main NE faults form NNE compression and NWW tensile after left-lateral shearing, which makes the several groups secondary NNE trending fault open and mineralization. |
| Keywords: | Bridge Structure Fault Echelon Vein Metallogenic Prognosis |
