胶东西涝口金矿区层间滑动构造与成矿

通过分析西涝口金矿区内层间滑动构造破碎带地质特征、地球物理特征、地球化学特征，并与典型金矿床基本地质特征进行对比，认为研究区内层间滑动破碎带具双层结构和多层滑动特点；上下主裂面附近破碎蚀变带发育在富含石墨和脆性大理岩层位；石墨可以改变含金热液氧化还原条件使成矿物质沉淀，大理岩的易碎性和活泼性易于矿液充填、交代。指出层间滑动破碎带对金成矿具有重要的控制作用，是区内重要的导矿和容矿构造。

Interlayer gliding structure and mineralization of Xilaokou gold field, East Shandong

Through analyzing the feature of geology, geophysics,geochemistry of the interlayer sliding fracture zone in Xilaokou gold field and contrasting the fundamental geological characteristics with the typical gold deposit. Author think that, in the studied area, the interlayer gliding fracture zone have two ply structure and many ply gliding trait;the broken alteration zone adjacen to its upper or under major fault grow respectively in layer of containing abundant graphite or crispy marble;the graphite can precipitate ore forming materials through changing oxidation reduction conditions of gold containing thermal fluid;the fragility and activity of marble benefit ore forming fluid clotting and replacing.This paper points that the interlayer gliding fracture zone plays important controlling role of gold mineralizing which is the important ore guiding and ore containing structure in this gold field.
