摘要
勉县七里沟地区位于汉江大断裂与略褒大断裂交汇部位的勉略阳三角区内,各种褶皱与次级断裂构造发育,侵入岩及各种脉岩分布广泛,并产出有小型铅锌重晶石矿及铜金矿点。通过对区内地层、构造、岩浆活动、变质作用、矿化特征的综合分析,结合R型聚类分析结果、构造地球化学特征及区内断裂构造控矿特点,划分出南部七里沟—艾叶口多金属成矿区和北西部张家坪—黑沟铜金成矿区两个有望找矿区段,初步认为本区具有寻找大型有色金属矿的基本条件。
Qiligou area of Mianxian is located in the Mianlueyang triangle area of the intersection of Hanjiang and Luebao big faults. Diversified folds and subsidiary fractures developed well. Intrusive rocks and various dikes are widespread and some small sized barite and copper ores occur. Based on the integrative analysis of stratigraphical condition, tectonic condition, magma activity, metamorphism and mineralization feature, combining the result of R-cluster analysis and the tectonic geochemical feature and the character of the ore-controlling faults in the area, the authors mark off two hopeful exploration areas, namely, Qiligou-Aiyekou polymetallic mineralization area in the southern part and Zhangjiaping-Heigou Cu-Ag mineralization area in the Northwest part. And it is possible to prospect a large-scale non-ferrous metal deposit in this area.
