Study on Space-Time Relationship of Tungsten and Uranium Mineralization

The metal organic series in Southern Jiangxi is the series of W & U deposits closely related with the Late Yanshanian granite within the South China fold system and the uplift belt. The host rock of W mineralization is fine or medium-fine grained biotitic granite of Early Yanshanian period, subordinated with Late Yanshanian granite The time initial of uranium concentration span from 103-70Ma. Vertically the mineralization zone of tungsten is above that of uranium, however horizontally it is in the center and that of uranium outwards. To the west of Wuyi tectonic belt, distinctly the uranium mineralized posterior to the tungsten, however to the east of Wuyi tectonic belt, the W-Mo-bearing grease negation quartz vein let remarkably cut off the U-bearing silicified fractured zone.
