矿化空间的有序性与矿体定位预测——以山东乳山地区石英脉型金矿为例

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。

Orderly rule of space distribution of mineralization and location prediction of orebody

The application of the orderly rule of mineralization space distribution in the location prediction of orebody with the example in Rushan region is discussed.The gold mineralization in Rushan can be diveded into two types,Rushan type and Tongling Type,and the former is the main one.Rushan type of gold minralization are mainly distributed in four NNE striked which manifest feature of left lateral and right stepover,the gold bodies of the adjacent gold deposits distributed in the same fault show opposite direction of dip trend.The gold deposits occurred within four left lateral and right stepover faults have the features of zoning in NNE extending and rowing in NE striked.NNE and NE striked faults jointly controlled the position of the gold deposits.The edges of the tortuous segments of the left lateral and right stepover fault,are the favorable areas of searching large gold deposits.Tongling type gold mineralization are controlled by the intrusive body structures formed in the course of Sanfushan porphyritic monzonitic granite intrusives.We also give an example of the use of mathematical characteristics of the main orebody in Chujiagou Gold Deposit.
