| 中文摘要: |
| 胶东破头青断裂带是招(远)－平(度)断裂带北段的主要金矿成矿断裂之一,先后发现了台上、东风171号脉、水旺庄、栾家河等大型金矿床。本文通过综合整理与分析以往的地球物理、地球化学、矿产勘查找矿等相关资料,建立了断裂带内矿化蚀变的三维空间模型,总结了构造蚀变叠加变化与矿床分布特征的相关性。基于玲珑杂岩体对成矿的影响范围,结合本次大地电磁测深(MT)的深部构造探测,推定破头青断裂为招平断裂带北段的主断裂,既是导矿构造又是容矿构造；栾家河断裂与破头青断裂的空间关系影响了破头青断裂内矿体的空间展布,预测深部仍有较好的找矿前景。 |
| 英文摘要: |
| The Potouqing fault in Jiaodong is one of the main metallogenic zone in the northern section of the Zhao-Ping fault zone. Many large gold deposits have been successively found,such as the Lingnan Taishang, Dongfeng 171 vein, Shuiwangzhuang, Luanjiahe, etc.Through the analysis and arrangement of related mass data including geophysical, geochemical, and mineral exploration, this paper builds the three-dimensional model of mineralization-alteration in the fault, and summarizes the correlation between the superposition of structural alteration and the distribution of deposit. Based on the influence scope of Linglong complex body on ore-forming, it can be inferred that Potouqing fault is the main fault in the northern section of Zhaoping fault zone,combining the detection of deep structure by MT. It is the ore-controlling and ore-hosting structure. The spatial relationship between Luanjiahe fault and Potouqing fault influenced the distribution of orebody in the Potouqing fault, which predicts a good exploration prospect in the deep. |
