Geology and geochemistry of the Nibao gold deposit in Guizhou

The Nibao gold deposit in Guizhou consists of multistory gold ore bodies,each of which is closely associated with the Permian volcaniclastic rocks.The examination of geology,geochemistry and fluid inclusions from the gold deposit has disclosed that the pseudoconformity between the volcaniclastic rocks and Dachang quartzite occurs as the main accommodation spaces. The gold mineralization age can be traced back to the Late Jurassic.The formation of the gold deposit is interpreted to be related to the local reactivation of the residual parts of the Emei mantle plume during the Yanshanian.
