招平断裂带北段构造控矿特征及找矿方向

Tectonic Orecontrolling Characteristics and Prospecting Direction in Northern ZhaoyuanPingdu Fault Zone

摘要:

招（远）平（度）断裂为胶东西北部三大控矿断裂之一。招平断裂北段玲珑金矿田范围内，向北分为NNE向九曲蒋家和NEE向破头青断裂，该文以它们的交会部位至2条断裂带在玲珑金矿田的结束部位及其所控金矿脉为主要研究内容，通过对招平断裂北段地质构造特征的研究，分析了招平断裂北段的形成和控矿机制，提出了破头青断裂不是控矿断裂的新认识，总结了该区金矿的赋存规律，预测成矿有利部位，提出找矿方向。

Abstract:

ZhaoyuanPingdu fault is one of three orecontrolling faults in northwest of Jiaodong peninsula. Northern ZhaoyuanPingdu fault in Linglong gold mine is divided into Jiuqujiangjia fault with the trend of NNE and Potouqing fault with the trend of NEE. In this paper, the area from the intersection between the two fault zones to their ends in the gold mine as well as the gold veins under their control have been studied. Through study on geological characteristics of northern section of ZhaoyuanPingdu fault, the formation of this section and its ore controlling mechanism have been analyzed. It is denied that Potouqing fault was not orecontrolling fault. Based on these analysis, the occurrence rule of gold ore has been summarized, favorable metallogenic zones have been predicated, and prospecting direction has been proposed in this area.
