摘要
本文从幔枝构造成矿控矿的视角,依据上石矾金矿一孔之见以及野外的详细观察和室内的综合分析,总结归纳出成矿作用特征和控矿因素,提出成矿地质模式,明确预测较为密集的网脉状矿体之下应该还有脉状矿体,甚至断裂蚀变岩型矿体,并通过矿田构造解析,指出上石矾矿区位于阜平幔枝构造西北缘拆离带上盘,上寨构造岩浆活动中心的倾伏端,具有优越的成矿条件,且矿化显示明显,预示出很好的找矿潜力,并大胆指出了中深部地质找矿验证的钻孔位置。
This article from the mantle branch structure ore-forming and ore-controlling perspective ,on the basis of Shangshifan gold deposit a peephole view and field detailed observation and indoor comprehensive analysis, summarized the mineralization characteristics and ore-controlling factors, proposed metallogenic geologic models, clearly predict relatively dense net veined orebody under that there should be a vein,or even fracture altered rock type deposit,and through the structure of ore field parsing,Fuping mantle branch northwest edge of the detachment to bring the disk that Shangshihan mining area is located,Shangzhai structure tectonic magmatic activity center plunging end, superior mineralization,and obvious mineralization shows a clearpredictive of good prospecting potential,and boldly pointed out deep geology prospecting borehole position verification.
