招平断裂带中段构造控矿规律及找矿意义

Ore Controlling Regularity and Prospecting Significance in Middle Section of ZhaoyuanPingdu Fault Zone

摘要:

招平断裂带位于胶西北隆起区东南缘，是我国最重要的金成矿区之一，其中段发育有大尹格庄断裂带、后仓断裂带、南周家断裂带、栾家河断裂带等，这几条断裂带对招平断裂带均有明显的错断现象，对还原金矿床有良好的指导作用。通过对几条构造的研究，结合成矿地质背景、矿床成因的研究，对该区的成矿规律、构造控矿规律进行探讨，指出了招平断裂带中段深部找矿远景。

Abstract:

ZhaoyuanPingdu fault belt is located in southeastern margin of Jiaobei uplift. It is the most important gold metallogenic zone in China. Dayingezhuang fault belt, Houcang fault belt, Nanzhoujia fault belt and Luanjiahe fault belt developed in the middle section. These fault belts have an obvious disconnection phenomenon. It has good guidance for reducing gold deposits. Through study on several structures, combining with the study on metallogenic geological background and the genesis of gold deposit, metallogenic regularity and ore controlling regularity of this area have been discussed, and deep prospecting prospect in middle section of ZhaoyuanPingdu fault belt has been pointed out.
