通过对陕西省凤县八卦庙超大型金矿床储矿构造的矿物地球化学研究认为 :泥盆纪时 ,在银母寺—八卦庙—八方山三级构造热水沉积成矿盆地中形成了金矿源层。海西晚期在古地热异常背景下 ,金矿源层发生顺层韧性压剪切变形 ,印支期脆 -韧性挤压剪切变形构造过程中金发生富集成矿 ,燕山期脆性变形 -深源热流体叠加成矿富化。该金矿床属含金脆 -韧性剪切带型金矿床 ,多源多期次含矿热流体同位叠加成矿作用说明八卦庙超大型金矿床是寻找非常规超大型金矿床的远景区
Based on the mineralogical and geochemical study of the ore-hosting structure of the Baguamiao super-large gold deposit in Fengxian County, Shaanxi Province, it is considered that during the Devonian period, gold was formed in the hydrothermal sedimentary mineralization basin of the Yinmusi-Baguamiao-Bafangshan tertiary structure Source layer. In the Late Hercynian anomaly background, paleo-bedding ductile shear deformation occurs in the gold source layer. During the Indosinian brittle-ductile shear deformation process, gold is enriched and mineralized, and the Yanshanian brittle deformation Thermal fluid superposition mineralization enrichment The gold deposit is a gold-bearing brittle-ductile shear zone type gold deposit. The isotopic superposition of multi-source ore-bearing fluids indicates that the Baguamiao super-large gold deposit is a prospect for finding unconventional super-large gold deposits
