摘　　要：攀枝花石墨矿区分布于上扬子古陆块康滇前陆逆冲带康滇基底断隆带中段。石墨矿床一般经历了沉积、区域变质改造以及后期热接触变质叠加改造三个阶段。攀枝花石墨矿的关键控矿构造为褶皱构造,其次为断裂构造,均属于后生构造,攀枝花石墨矿床分布受区域构造控制成群产出,形成矿集区。在控矿构造研究的基础上,构建“层带复合-岩浆叠加”的区域找矿预测地质模型。Panzhihua graphite deposit is located in the middle part of Kangdian basement fault uplift zone in Kangdian foreland thrust belt of the Upper Yangtze Paleocontinent Block.Graphite deposits generally undergo three stages:sedimentation,regional metamorphism and superimposition of thermal contact metamorphism.The key ore-controlling structure of Panzhihua graphite deposit is fold structure,followed by fracture structure,which belongs to epigenetic structure.The distribution of Panzhihua graphite deposit is controlled by regional tectonics,forming ore concentration area.Based on the study of ore-controlling structure,a regional prospecting and prediction geological model of"layer-zone composite-magma superimposition"is constructed.
