The Luocheng copper deposit of Wanzai country is located in the South of Jiuling uplift, west section of Yifeng-Jingdezhen plate edge deep. The copper ore body is produced in the upper section of the Yifeng(rock) group(Pt_3~(la)y~2), which is controlled by the northeastern tectonic deformation. The ore body is mainly produced in the inter-layer fractures, fault structures, showing the characteristics of fracture structure ore control. The uniform temperature and salinity of the fluid inclusions in the ore indicate that the mineralization should have two stages, The first stage for the submarine volcanic jet effect, the second stage for the late metamorphic hydrothermal superimposed transformation. Comprehensive regional geological characteristics, mining area geological characteristics, ore body characteristics and the above experimental results, obtained that the deposit should be marine-volcanic jet deposition metamorphic copper deposits.
