Abstract
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.
