摘　　要：丑泥口金矿位于太行山中段麻棚岩体南侧,是麻棚地区近年发现的重要金成矿靶区。区内成矿地质条件优越,以分布密集、规模较大的近SN、NW向矿化蚀变破碎带为特征。结合区域成矿地质背景,以幔枝构造理论为指导,通过分析矿区地质特征,指出断裂是该矿床重要的控矿因素;金矿成矿物质主要来源于地球深部,成矿溶液以岩浆水为主;在燕山期强烈的阜平幔枝构造活动期间,深部成矿物质可搭载麻棚岩体向上迁移,至浅部近SN、NW向破碎带等有利构造部位富集成矿,在此基础上提出了今后找矿方向。Chounikou gold deposit is located on the south side of Mapeng granitic intrusion in the middle of Taihang Mountains,and is an important gold metallogenic target area discovered in recent years in the Mapeng area.The ore-forming geological condition is superior in the area,which is characterized by the near SN trending and NW trending mineralized alteration zones with intensive distribution and large scale.On the basis of taking the mantle branch structure metallogenetic theory as a guide and analyzing the geological characteristics of the mining area,the paper points out the faults are the main ore-controlling factors of the deposit;the ore-forming materials are mainly from the deep earth and the mineralization-solutions are mainly from the magmatic water;during the strong tectonic activity of Fuping mantle branch structure in the Yanshanian period,the deep ore-forming material which could be carried in the Mapeng granitic intrusion,migrated upward to the shallow favorable structural position of SN trending and NW trending fracture zones,ect.,for the enrichment and the mineralization.On the basis of this,it puts forward the future prospecting direction.
