矿区所处大地构造位置为西秦岭褶皱带北部断褶带与中部裂陷槽之间的过渡部位,位于合作—岷县区域断裂带上。该矿床地处同仁-夏河-岷县金成矿带[1]。1矿区地质特征矿区地层主要为三叠系中统古浪堤组下段(T2g1)钙质、粉砂质、泥质板岩组成的细碎屑岩为主要赋矿围岩,属陆棚斜坡相
The tectonic location of the area where the mine is located is the transitional part between the northern fault fold in the western Qinling fold belt and the central rift groove, and is located on the fault zone of the cooperation-Minxian area. The deposit is located in Tongren - Xiahe - Minxian gold metallogenic belt [1]. 1 Geological Characteristics of the Mining Area The strata of the mining area are mainly composed of fine clastic rocks composed of calcareous, silty and argillaceous slate in the lower part of the Triassic Gurongti Formation (T2g1)
