摘　　要：拾金坡-金场沟金成矿带是北山地区最重要的金成矿带之一,成矿带内已发现金矿化线索38处,中小型金矿床9处,均与中酸性岩浆岩有关,主要成矿类型有岩浆热液型和矽卡岩型,其中岩浆热液型金矿是成矿带最主要的成矿类型。优选拾金坡金矿床和金场沟金矿床作为拾金坡式金矿的典型矿床,通过分析矿床的成矿地质环境、矿体特征、矿床成因和成矿模式等,建立了成矿带区域成矿模式。成矿模式的建立,将有助于促进对矿床成矿规律的认识,明确该成矿带金矿找矿方向。Magmatic hydrothermal gold deposit is the most main metallogenic types in Shijinpo-Jinchanggou gold metallogenic belt which is one of the most important gold metallogenic belt in Beishan area. 38 metallogenic clues and 9 gold deposits related to magmatic activity have been found in this metallogenic belt. The main types of mineralization are magmatic hydrothermal type and skarn type, in which magmatic hydrothermal type gold deposit is the main metallogenic type of this metallogenic belt. Analyzing the geological environment, ore-body characteristics, ore deposit genesis and metallogenic model of Shijinpo and Jinchanggou gold deposits, as the typical ore deposit in Shijinpo-Jinchanggou gold metallogenic belt, the regional metallogenic model is established, Which will effectively promote the studying of deposit metallogenic regularity of gold deposits and clearing the prospecting direction.
