ORE-CONTROLLING STRUCTURAL DEFORMATION AND ITS RELATION TO THE METALLOGENESIS IN DABEIWU GOLD ORE FIELD IN JIANGXI PROVINCE

By study on the features of foliation and lineation structures in the Dabeiwu gold ore field in Jiangxi Province, with correlative rock and mineral testing, the structural deformation facies are established corresponding to the regional tectonic development. The relationship between the ore-controlling structural deformation and the metallogenesis is analyzed. It is concluded that, the gold deposit is formed by the enrichment of useful elements during the structural superimposition in the core of Zhanggongshan terrain in the south of Jiangnan massif (old land) on the southeast margin of Lower Yangtze plate, with a series of structural deformations from deep-medium level to shallow level.
