摘要
矿区大地构造位置属秦岭—大别造山带中段,北秦岭构造带,区内地层为一套中浅变质火山—沉积岩系,地质构造复杂,成矿地质条件优越。歪头山组中部(Pt3w2)第二岩性段(Pt3w22)为矿区主要含矿层位,朱庄背斜是矿区的一级控矿构造,矿床的成因类型为变质岩来源大气降水热液金矿床。研究成果对矿区以后地质勘查工作具有很重要的指导意义。
Mining area belongs to the middle qinling-dabieorogenic belts.North Qinling tectonic beltin a shallow strata will be in the metamorphic volcanic sedimentary rock series.The complex geological structure and metallogenic geologic condition is superior.The central mountain group（Pt3w2） in the second lithologic section（Pt3w2^2） is about the main mining area of ore-bearing bed.Zhuchuang anticline is primary in ore-controlling tectonicgenesis of ore deposit types of metamorphic origin of meteoric hydrothermal gold deposits.The research of mining area geological exploration has important guiding significance to the future.
