以山东乳山地区石英脉型金矿为例 ,探讨了一些矿化空间有序性规律在矿体定位预测中的应用 ,乳山地区石英脉型金矿可分为乳山式和铜岭式 2种类型。其中乳山式金矿分布于 4条陡倾的 NNE向左行右阶式压扭性断裂带上 ,矿体定位受 NNE及 NE向断裂的联合控制 ,具 NNE向成带、NE向成行的特点 ,沿同一控断裂带上分布的相邻金矿床 ,其矿体侧伏方向是相反的。利用这种矿化空间分布的有序性规律 ,在老青—小青地区发现了金矿体。在矿体数学特征研究方面 ,根据初家沟金矿一号矿体的品位和厚度变化趋势分析 ,研究并发现了采空区下部的隐伏矿体。
Taking the quartz vein type gold deposit in Rushan area of Shandong Province as an example, the application of some mineralization spatial order rules in the prediction of orebody locality is discussed. The quartz vein type gold deposits in Rushan area can be divided into two types: Rushan type and Tongling type . Among them, the Rushan-type gold deposits are distributed on four steeply inclined NNE left-row right-order compressive fracture zones, and the ore body locates under the joint control of NNE and NE faults with NNE to zone and NE line formation , The adjacent gold deposits distributed along the same controlled fault zone have the opposite direction of the side volt. Using the regularity of the spatial distribution of mineralization, gold ore bodies were found in the Laoqing-Xiaoqing area. In the aspect of ore body mathematical characteristics, based on the analysis of grade and thickness trend of No. 1 orebody in the Qijiagou Gold Mine, the concealed ore body in the lower part of the goaf is studied and discovered.
