摘　　要：对江西江背萤石成矿地质特征和控矿地质条件及找矿标志进行了分析,认为成矿作用与区内燕山期构造-岩浆活动、震旦纪及白垩纪地层有密切联系。矿区位于南岭东西构造带所属的兴国-石城构造带与武夷山所属的于山构造带复合部位,江背花岗岩体内接触带,与中酸性-酸性岩浆岩有关。矿体赋存燕山期似斑状中粒黑云母花岗岩中,成矿作用受区内主干断裂及与其有关的次级断裂控制,主要分布于F1断裂带东侧附近及300 m范围次级构造中。查明区内成矿作用与成矿规律对今后找矿具有指导意义。The fluorite deposit in Jiangbei, Jiangxi province are analysed by geological characteristics, conditions and prospecting, which indicates that the mineralization is closely related to the Yanshan tectonic and magmatic ac- tivity, and the Sinian and the Cretaceous strata. The study area located in the composite parts of Nanling latitudinal tectonic belt which belongs to Xingguo-Shicheng belt and Wuyishan which belongs to Yushan belt. The ore bodies are hosted in the contact zone of Jiangbei granite which are the Yanshan period of porphyritic biotite granite in grain, and the mineralization is controlled by the main fault zone and its related secondary fracture, which manily distributed in the F1 fault zone on the eastern side of secondary structure and near the 300 meters range. Find out the area mineralization and metallogenic regularity has guiding significance for prospecting.
