| Abstract: | The structures in Fongzichong lead-zinc orefield in Guangxi are controlled by Bobei-Cenxi fault zone. The NE striking structures formed in early phase are mainly of compression, and the NNE striking structures formed later are mainly of horizontal shear and also of compressive characteristics. The mineralization of this orefield relates to the extensional stress field over late Diwa stage. Through comprehensive analyses on the petrofabrics, limited strain measurement and joints, the author puts multiperiodic and complex history of the orefield's structural development in order. |
