Fractal Character of Structural Control on Uranium Mineralization in South China

Abstract:

Article Preview

South China is the most important uranium producer in the country. Most uranium deposits in south China are strictly controlled by NE-NNE trending regional fracture structure. Fractal analyses on spatial distribution of uranium deposits and regional fracture structure in south China have been done in this paper. It indicates that the spatial distribution of both uranium deposits and regional fracture structure in south China show fractal character. The fractal dimension D=1.4142 for the spatial distribution of regional fracture structure is significantly greater than the critical value and it indicate a higher ripening degree in the fracture structure evolution and an advantages to fluid flow and uranium mineralization. The fractal dimension D=1.0527 for the spatial distribution of uranium deposits in south China show a lower complexity than regional fracture structure. The fractal spatial distribution of uranium deposits in south China is the result of the evolution of the fractal fracture structure system.
