摘要
萑香洼金矿床产于华北陆块南缘中元古界熊耳群火山岩系中 ,矿床严格受断裂构造控制。本文根据区域和矿区断裂构造特征 ,分析了萑香洼金矿床不同构造层次对金矿的控矿作用 ,总结了断裂构造的控矿特征 ,认为区域性深大断裂 (Fm、Fs、F1)为导矿构造 ,控制金矿带、矿床的分布 ;次级的NW向 (F985等 )和近EW向 (F14等 )断裂构造为主要容矿构造 ,控制矿体的产出 ;NNE向 (F2 0 1等 )断裂为成矿后构造 ,起破矿作用。容矿断裂在主成矿期经历了“挤压—拉张”的脉动式活动 ,具“韧—脆性”
The studied gold deposit, located in Huanxiangwa village, Songxian County, Henan Provice, occurs in the volcanics of the Mesoproterozoic Xiong'er Group in the southern margin of the North China platform. The deposit is strictly controlled by faulted structure. The large and deep regional faults are the ore-leading fracture, controlling the distribution of the gold deposit and mineralization zone. The secondary faults with NW and nearly E-W strike are the main ore-bearing structures, controlling the occurrence of orebodies. According to the feature of the faulted structure in the region and field, the ore-controlling function of the different structual order to the gold deposit is analysed in the paper, and the characteristics of the faulted structures is summurized as well.
