摘　　要：研究区属于北巴颜喀拉山金、锑成矿带中段,是我省重要的成矿带。大场金矿总体处于大型倾伏背斜构造的转折端,是断裂构造形成的断块后缘张性环境下的产物,主要赋存在中三叠世巴颜喀拉山群板岩夹砂岩组(T2B2)中。通过对大场金矿的地球化学特征、构造和成矿机制的分析,明示了找矿潜力和该矿区下一步的找矿方向,其找矿前景十分广阔。The study area belongs the middle of gold--antimony metallogenic belt in the north of BaYanKaLa mountainthe ,which is an important metallogenic belt in our province. Dachang gold deposit is formed by the fracture structure after a margin fault block in the side of the turning point of the large plunging anticline structure, mainly occurs in the slate sandstone group （T2B2） of the Middle Triassic BaYankala group. Through the study of geophysical and geochemical characteristics and structure and Metallogenic mechanism analysising the prospecting potential of dachang gold deposit and expressing prospecting direction of the mine the next step, and its prospecting potential is very broad.
