摘　　要：赣北"九瑞"和彭山地区,因其独特的构造样式和矿床成因类型,很少有人将其合为一体系统分析。作者从研究该区最基础的沉积建造、构造特征和矿床形成的基本方式入手,结合边界深大断裂的活动特点及区域大地构造的演化规律,认为垂直运动是导致两地构造与成矿明显不同的主要原因,亦是该区岩浆定位和矿床(体)形成的主要机制。区内"特定地层、构造、岩体综合控制型"和"岩体底辟侵位控制型"两种"矿床式"正是这种构造长期递进变形和变形分阶段演化的结果。The Jiujiang Ruichang,north and Pengshan areas in northern Jiangxi province have their own unique tectonic styles and genetic types of ore deposit formation. Because of this reason, it is generally underappreciated by researchers that these two areas should be analyzed as one system. We be- gin with the study of the most basic sedimentary formation, structural features and the primary styles of the formation of deposits, combining the activitiy characteristic of the marginal deep faults and the tectonic evolution law of the region to explore this system. Our conclusion is that the vertical motion is the main reason for the significant difference between these two areas in structure and mineralization. Tile main mechanism of magma emplacement and mineral deposit（body） formation in these two areas is also the vertical motion. The two deposit types, ＂joint control by special strata, structure and rock bodies＂ and ＂ control by rock diapiric emplacement＂ , are the result of this mechanism in its long-term progressive deformation and stage-wise evolution of deformation.
