| Abstract: | Based on the study of structural analysis and tectonic evolution of NNE trending strike slip fault zones in Hunan-Jiangxi border region,and ore forming fluid migrating process in the strike slip fault system,the mechanism and evolutive features of hydrothermal uranium mineralization are detailed.The NNE trending strike slip fault system is a integrated field of tectonic fluid metallogeny in Hunan-Jiangxi border region,and controlled the formation and location of uranium deposits on time and space.Some uranium deposits are closly related to hydraulic fracturing.With the study of structural style and fractile geometry of the NNE trending strike slip fault system,the authors calculate the fractal values ( D ) of different associated fault patterns of the mine,discuss the coupled relation between structural deformation and fluid activity in strike slip fault zones,and summarize the models of fluid flow and hydrothermal U mineralization and the process of U metallogenic dynamics. |
