八卦庙及外围金矿控矿因素与富集成矿规律研究

简述了凤太矿田中的典型构造蚀变岩型金矿床——八卦庙金矿的基本特征；初步分析了八卦庙金矿、丝毛岭金矿的地球化学特征，推测丝毛岭金矿点的成矿模式可能与八卦庙金矿床的成矿模式不同，或者是同一成矿系统中的不同成矿系列，而不同深度原生晕聚类分析谱系图显示，八卦庙金矿床随着深度的增加Au与亲岩浆（幔源岩浆）的元素相关性趋于密切，表明八卦庙金矿床的成矿有岩浆参与。重点研究了风太矿田中八卦庙及外围金矿的控矿因素——控矿构造特征、控矿地层及其岩性特征、矿化蚀变特征等，并以八卦庙金矿、柴蚂金矿为基础，总结归纳了八卦庙及外围金矿的富集成矿规律，进一步指明了八卦庙外围金矿的找矿方向及其找矿潜力。

Ore-Control Factors and Gold Enrichment in the Surroundings of the Baguamiao Gold Deposit

This paper briefly introduces the characteristics of the Baguamiao gold deposit belonging to a typical gold deposit of tectono-alteration rock. Based on initial analysis of geochemical features for the Baguamiao and the Simaoling gold deposits, it can be inferred that the Baguamiao gold deposit and Simaoling gold deposit probably are different from each other in terms of the metallogenic model. They may be different metallogenic subsystems in the same system. The dendrogram on cluster analysis of primary halo at variously depth in the Baguanmiao gold deposit reveals that the correlation between Au and magmatophile elements is getting closer and closer as the depth increases, reflecting magma participated in gold mineralization in the Baguamiao deposit. It focuses on the ore-control factors in the deposit and the surrounding area, including ore-control structures, strata as well as lithological and alteration. The enrichment characteristics have been summarized based on both the Baguamiao and Caima gold deposits and furthermore prospecting potential and direction are pointed out.
