摘要
大尹格庄金矿床矿体空间定位规律系统研究结果表明,已探明主矿体均产于招平断裂带内,NEE向次级断裂对主矿体空间定位有明显控制作用,与招平断裂带主裂面平行的次级断裂构造常产出小规模富矿体,招平断裂带深部派生的"入"字形构造有利于富矿体的产出,构造岩(碎裂岩、糜棱岩)和断层泥厚大部位矿体厚度增大;已探明矿体北东侧伏方向上是深部隐伏矿体的有利定位空间。据此圈定的成矿预测区,经工程验证,探矿增储效果明显。
The systemic research on the orebody locating rules of Dayin＇ gezhuang gold deposit was carried out in this paper. The results show that （1） the main orebodies are located in the Zhaoping Fault Belt （ZFB）, （2） NEE secondary faults control the orebodies＇ locating, （3） the small ore shoots are often located in the secondary faults parallelling the ZFB, and （4） the ＂A＂ style structures derived by the ZFB are propitious to the rich-orebodies to locate in. Moreover, the ore bodies usually locate in the places where the thickness of structural rock is much thicker than other places. Generally, NE lateral trending direction of orebodies is favorable areas for deep concealed mineral prospecting. According to these rules, a number of ore bodies were found out through exploration.
