摘要: |
胶西北地区是我国最大的金矿矿集区,深入研究其构造控矿特征对于揭示成矿规律具有重要意义。在总结前人对胶西北地区相关研究的基础上,构建胶西北矿集区三山岛断裂、焦家断裂和招平断裂的三维模型并进行定量空间分析,得到了与构造控矿模型相对应的控矿因素指标。在数据驱动视角下,从空间数据出发,分析控矿因素指标与矿化指标间的关联,挖掘数据背后所体现的定量化证据,揭示了胶西北矿集区断裂距离场及断裂形态特征的控矿规律。 |

Abstract: |
Northwestern Jiaodong Peninsula is the largest gold ore concentration area in China. It is of great significance to study its structural ore-controlling characteristics for revealing metallogenic regularity. On the basis of summarizing the previous researches on northwestern Jiaodong Peninsula, the three-dimensional models of Sanshandao fault, Jiaojia fault and Zhaoping fault in northwestern Jiaodong ore concentration area were constructed and analyzed quantitatively, and the ore-controlling factors corresponding to the structural ore-controlling model were obtained. From the data-driven perspective, the correlation between ore-controlling factors and mineralization indexes was analyzed based on spatial data, the quantitative evidence reflected in the data was mined, and the ore-controlling law of fracture distance field and fracture morphology characteristics in the study area was revealed. |
