The mineralization of hydrothermal uranium deposit is very complicated. The structure is one of the most important ore-controlling factors. In the study,the structures are chosen from China-Brazil Jianbing 3 # high spatial resolution remote sensing interpreted da-ta. ARCGIS9. 2 and ARCVIEW3. 2 software are used to analyse structure’s fractal charac-teristics in Zhuguang area. The relation between structure’s fractal characteristics and ura-nium mineralization is also studied. The result shows that there is a good corresponding re-lation betwe...
