河南桐柏银洞坡金矿区地质特征与成矿机理研究

摘要

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(Pt3w22)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.%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.
