摘要
通过研究断裂的几何特征、构造特征等,分析区域应力场和矿区构造应力场,揭示九丈沟金矿床控矿构造规律。九丈沟金矿床矿区位于华熊台隆西缘,马超营断裂带北侧。区内NE向深大断裂(F1)构造以导矿为主,局部容矿,并总体控制各成矿带分布,次级NW向构造则以容矿为主,并与NE向次级构造复合控制金矿床、矿体的产出。控矿断裂F1具有明显构造控矿的层次性和规律性及构造活动多期次的特点。
Through researches on geometrical and tectonic characters of fracture, analysis on regional stress field and tectonic stress field of ore district, the rule of ore body controlling of Jiuzhanggou Gold Deposit is revealed. This gold deposit is located on the west of Huaxiongtai promontory and the north of Machaoying fracture zone. Within the field, NE large rupture (F1) which is mainly of ore conforming, locally of ore bearing controls the distribution of every metallogenic belt. Sub- NW structure which is mainly of ore bearing co-controls the output of gold deposit and ore together with NE sub-structure. Mine-controlling rupture (F1) has obvious arrangement, orderliness and the character of multi-periods of tectonic activities.
