摘　　要：内蒙古赤峰市柴胡栏子金矿是一座以蚀变岩型为主、石英脉型为辅的中型黄金矿床,控矿构造研究表明,矿区内构造可划分为导矿构造、运矿和容矿构造;运矿和容矿构造发育在导矿构造两侧120m范围以内,并直接控制着矿体的空间产出形态;成矿后期发育的NE向和近EW向的构造常被脉岩充填并切穿和错动矿体,但总体断距不大。因此其主要找矿方向应是寻找导矿构造的隐伏延伸部分以及两侧的运矿和容矿构造,并根据此认识在矿区外围钻探获得了工业矿体,使找矿工作取得了突破。Chaihulanzi gold deposit in chifeng city, Inner Mongolia is of medium size, with altered rock type as the main type and quartz vein type, the auxiliary. The investigation of its ore- controlling structures shows that the ore-controlling structures in this area can be devided into ore-transmitting, ore-carrying and ore-depositing types. The ore-carrying and ore-depositing structures are distributed within 120 m wide range along both sides of the ore-transmitting structure and directly control the spacial occurrence shape of the orebody. The NE and near EW direction structures developed in the later period of ore formation are frequently filled by the vein rock and the ore body is cut or staggered, but with not large fracture distance on the whole. Therefore, the main ore-prospecting driection should be to look for the hidden extending part of ore-transmitting structure and the ore-carrying and ore-depositing structures along its both sides. A new orebody has been found by drilling in the periphery of the mine district according to this understanding gaining a breakthrough in ore prospecting.
