The role of geochemical barriers in Guangxing area uranium mineralization

In the late Mesozoic, the deep source hydrothermal activity moved out the uranium in the basement and moved up along the fault structure. The migration process was precipitated by the geochemical barriers. The geochemical barriers in Guangxing area include faults geochemical barrier, the contact zone of geochemical barrier, alteration zone geochemical barrier, all have a certain control on uranium mineralization. We can find out its control on uranium mineralization by analysing the contact between geochemical barriers and uranium ore bodies in the spatial distribution. lt has guiding significance for deep ore and metallogenic environments exploration.
