摘　　要：贺兰山北段是中国新兴的金找矿潜力区。在分析矿体地质的基础上,结合野外地质调查,从找矿角度详细划分了区内金的成矿类型,并系统分析了断裂构造体系对成矿的具体控制作用。综合成矿构造应力场、矿体(带)空间构型及成矿流体-物质场结构分析,指出了区内下一步找矿方向,强调勘查工作应以低缓石英脉型金矿床为重点对象,兼顾F1中构造破碎带蚀变岩型金矿床。Northern part of Helan Mountain is the emerging region for gold exploration with great potentials in China. The study carefully made out mineralization types existent in the district and systematically analyzed the specific ore-controlling effects fracture structure had on mineralization, with the help of geological analysis of orebodies and field investigation. Bringing the structural analysis of tectonic stress field, spatial structure of orebodies and ore-forming material field-fluid field into consideration, the paper points out the low and moderately inclined quartz vein as the main exploration target and altered rock type gold deposits in structural fracture zone of F1 also as important areas.
