| Abstract: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鄄
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. The 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 deforma鄄
