山东文登西岭西金矿矿床地质特征及成矿条件

Deposit Geological Characteristics and Metallogenic Conditions of Xilingxi Gold Mine in Wendeng District,Shandong Province

山东西岭西金矿区位于威海—文登成矿带内,该成矿带为胶东东部地区受米山断裂带控制的近SN向成矿带,断裂构造十分发育,金矿床(点)分布众多。研究区内主要的矿化蚀变带位于米山断裂的次级断裂内。通过对西岭西金矿区地质特征、地球物理特征、矿床地质特征进行综合分析,讨论了矿区成矿条件及找矿方向。研究表明:矿体赋存于米山断裂的次级断裂内,形态、产状受断裂构造控制;激电异常、岩石剖面与矿化体对应良好,槽探、钻探工程可有效揭露矿化体;区内金矿成矿条件优越,找矿潜力巨大。

Xilingxi gold mining area in Shandong Province is located in the Weihai- Wendeng met- allogenic belt. The metallogenic belt is a near SN metallogenic belt controlled by the Mishan fault zone in the eastern part of Jiaodong. The fault structure is very well developed and a large number of gold deposits （points） are distributed. The main mineralization alteration zone in the study area is located in the see- ondary fault of the Mishan fault. Through comprehensive study and analysis of geological characteristics, geophysical characteristics and deposit geological characteristics of the mining area, the metallogenic background of the mining area is understood in detail, and the metallogenic conditions and prospecting direction are summarized. The study results show that the orebody is located in the secondary fault of the Mishan fault,and its form is controlled by the fracture structure;the IP anomaly and the rock section are well corresponded with the mineralized body ;the mineralized body can be exposed by trenching and drill- ing engineering;the gold mineralization conditions of the area is good, the prospecting potential of gold de- posit in the area is huge.
