摘要

摘要: 在调查分析的基础上,结合变质核杂岩构造特征,研究了小秦岭金矿带潼峪矿集区金的成矿规律与控矿因素,指出潼峪矿集区金矿床的成矿物质来自太华群,并受晚期岩浆和构造的控制,尤其是变质核杂岩构造系统及其剥离(滑脱)构造控矿特征非常明显。综合研究认为,区内佛头崖-狮子包地段、东交沟—佛头崖一带、岳王庙-王排沟地区与复背斜倾伏端是重要的找矿靶区,值得进一步深入工作,并可为老矿区找矿提供示范。这对在老矿区深部寻找金矿,把小秦岭西段的深部找矿工作推向新阶段,实现找矿突破,具有重要的现实意义。

Abstract: On the base of survey and analysis, combined with feature of metamorphic core complex structure, we studied on the metallogenic regularity and ore-controlled mark for gold deposit in Tongyu ore cluster region of Xiaoqinling mineralized belt.The results show that the metallogenic substances come from Taihua group stratum, and gold deposits are controlled by late magma and structure, displayed clear ore-controlled characteristics of metamorphic core complex structure system and its stripping decollement structure.Fotouya-Shizibao, Dongjiaogou-Fotouya, Yuewangmiao-Wangpaigou district, and anticlinorium pitching end in this region are important exploration targets, needing further geological work, which can provide a model for exploration in old mine area.It has important practice significance for prospecting deep gold deposit in old ore region and making the deep gold exploration in west Xiaoqinling come to a new stage and achieving exploration breakthrough.
