CHARACTERISTICS OF ORE CONTROL FAULT SYSTEM IN XIAONANGOU GOLD DEPOSIT,HENAN PROVINCE

摘要: 河南熊耳山地区的金矿大多产于NE向和近E-W向断裂中.近年来发现的小南沟金矿受控于近S-N向断裂，开拓了该地区金矿找矿的新思路.研究表明，近S-N向的控矿断裂为NNW向与NE向一组共轭断裂的复合成因，是在E-W向基底断裂的基础上发育形成的，成矿作用与区域成矿具有一致性.总结出NE向断裂有利成矿的断裂走向勘探标志，指出小南沟金矿的外围仍有良好的找矿条件，NNW向、NE向与NWW向断裂构造交汇部位有利成矿.小南沟主矿体存在向北的迅速侧伏，侧伏的原因与E-W向断层北倾以及NNW与NE向断层交汇线的向北侧伏有关.Abstract: Most of the gold deposits in the Xongershan area,Henan province,occurr in NE-and E W-trending faults.But the recently discovered Xiaonangou deposit is in the fault running north-south,which appears to show a new approach for exploring in this district.The study on the fault system around the mine suggests that the S-N-trending fault controlling the orebodies is composed by the conjugate NE-and NNW-trending. Based on that,it is considered that the intersections of the faults running NNW,NE,and NWW,especially the fault along NE,are good ore-forming positions for gold deposits.The orebody sidepitches rapidly to north,which may be coursed by the pitching to north of the E-W fault or the cross line of the faults trending NE and NNW.
