洛宁南部金矿田位于豫西小秦岭-崤山-熊耳山金成矿带的东侧,矿产资源丰富,主要出露晚太古代片麻岩穹窿及盖层火山岩建造,总结了该区金矿成矿构造、地质特征、矿床成因及找矿方向,认为区内燕山期强烈的岩浆活动,为太华群地层中金的活化、迁移,富集提供了热动力,另外区内多组破碎带为金矿形成提供了良好的成矿空间,是重要的控矿因素,根据金矿的富集规律,提出了今后找矿与勘探的理论依据。

Southern LuoNing gold ore field is located in east of Qinling -Xiao Mountains -Xiong'er Mountain gold metallogenic belt in western He'nan province , rich in mineral resources , mainly with Late Archean gneiss dome and cap rock volcanics .This paper summarizes the gold metallogenic tectonics , geological characteristics , ore genesis and prospecting direction , pointing out that strong Yanshanian magmatic activity in the activation , migration and enrichment in Taihua Group provide thermodynamic . In addition, multiple sets of fracture zone in the area provide good ore -forming space for gold deposit formation, which is an important ore-controlling factor.According to the gold enrichment regularity , this paper puts forward the theory basis of prospecting and exploration in the future .
