摘　　要：大水大型金矿床,是大水—忠曲NWW向构造-石英闪长岩金矿床成矿带的重要组成部分,断裂构造控岩控矿特征明显。区域NWW向F1—F5断裂构造控制了大水格尔括合石英闪长岩体和金矿床的形成和分布;次一级近SN向、NNE向和NWW—EW向次级断裂构造及与区域NWW向F3—F5断裂构造交叉与复合,控制了大水格尔括合石英闪长岩体南侧4个石英闪长岩脉群和对应的4个金矿体密集区的空间分布;更次一级断裂构造又进一步控制了4个闪长岩脉群和对应的4个金矿体密集区每个闪长岩脉(枝)、金矿体的具体空间产出与就位。Dashui Gansu large gold ore deposits,is the important part of the Dashui-Zhongqu NWW strike faults-quartz diorites-gold deposit metallogenic belt.The characteristics of rock-ore-controlling by structure is obvious.the NWW regional faults（F1-F5） controlled the distribution of the quartz diorites in the south of the Ge-er-kuo-he and gold deposit;The subordination SN-NNE and NWW-EW strike faults and the convergent parts of different strike faults controlled the concentration distribution of the 4 quartz diorites group and 4 gold orebodies group.The secondary to the SN-NNW and NNE strike faults further controlled the spatial distribution of the specific quartz diorite and specific gold orebody.
