摘　　要：甘肃省狼娃山金多金属矿位于红石山—六陀山裂谷缝合带南侧狼娃山-白梁复背斜的南翼,通过区域背景、工作区成矿地质特征,分析了该工作区的控矿条件,认为金多金属矿受石炭系下统白山群的酸性火山岩、近EW向、NW向、NNW向断裂、石英脉、矽卡岩控制,其成因为中低温热液型成因的金多金属矿。主要找矿标志为构造蚀变带+石英脉+地层岩性。Gold polymetallic ore of Langwa Mountain in Gansu Province is located in the north limb of the Langwa Mountain-Bailiang anticlinorium in the south of Hongshi Mountain-Liutuo Mountain valley suture zone.Through the regional background,ore-forming geological characteristics in the work area,this paper analyzes the ore-controlling conditions.It is believed that the gold polymetallic ore is controlled by acid volcanic rocks in the lower carboniferous baishanqun,nearly EW,NW,NNW direction faults,quartz veins and skarn,and the orgin of deposit belongs to a gold polymetallic ore of low and medium temperature hydrothermal type.The main ore-prospecting indicators are tectonic alteration belt+quartz vein+stratigraphic lithology.
