摘要
阜平幔枝构造北东倾伏端 ,是轴部乌龙沟 -上黄旗韧脆性剪切带与外围主拆离滑脱带的交汇部位 ,断裂构造发育 ,岩浆活动强烈 ,成矿控矿有利 ,矿床类型多样。笔者以上明峪主拆离滑脱带型金矿、镰巴岭上盘盖层裂隙型铜铅锌矿和支家地上叠断陷盆地中次火山岩裂隙型银矿为例 ,讨论了幔枝构造外围主拆离滑脱带、上盘盖层密集裂隙带和上叠断陷盆地次火山岩构造的成矿控矿作用 ,总结成矿规律 ,归纳成矿模式。
The northeast plunging crown of Fuping mantle branch structure occurred the intersection of Wulonggou-Shanghuangqi ductile-brittle shear belts along this mantle branch axis and peripheral main detachment belts. It is very advantageous to ore-forming and ore-controlling, and have formed different typical deposits in this area, owing to development of fracture structures and strong magmatic activity. Exemplified by gold deposits in main detachment-slip zone, copper,lead and zinc deposits in cover fissures as well as silver deposits of subvolcanic fractures in overlapped fault basins. in this paper, we discuss briefly ore-forming and ore-controlling of the main detachment-slip zone, fractures in hanging wall cover and structures in overlapped fault basins. Then the metallogenic regularities and models was summarized and the prospecting targets were proposed.
