| 摘 要： | 焦家断裂带是焦家金矿田的控矿构造,已发现的焦家、新城、河东、河西、马塘、望儿山等大型金矿床均受该断裂带控制。焦家断裂带的次级断裂——河西断裂是一条重要的控矿断裂,但对河西断裂东段走向一直没有定论,困扰着矿山找矿实践和对成矿规律的研究。根据矿山探采资料,确定河西断裂东段为河东金矿上盘控矿断裂F1,与望儿山断裂相交会于182线附近,连通了焦家断裂和望儿山断裂。其控制的矿体均产于河西断裂与NE向断裂的交会处,产状平直地段矿化蚀变均较弱。

| Abstract: | Jiaojia fault belt is the ore controlling structure of Jiaojia gold field. Already found large scale gold deposits, such as Jiaojia, Xincheng, Hedong, Hexi, Matang and Wang''ershan are controlled by this fault. Hexi fault, the secondary fault of Jiaojia fault zone, is an important ore controlling fault, but the trend of east section of Hexi fault has no certain conclusion. According to mining exploration information, it is determined that the east section of Hexi fault is the F1 fault of the controlling fault of Hedong gold deposit. It intersects Wang''ershan fault at No.182 line, and connectes Jiaojia fault and Wang''ershan fault. The ore bodies all occur in the intersection part of Hexi fault and the fault with the trend of NE. The mineralization and alteration are weak in straight sections. |
