| Abstract: | The theory and implement process of fractal singular value decomposition method are introduced in the paper and applied to the granite-hosted uranium cluster areas in Taoshan.The uranium geochemistry field of Taoshan area at the scale of 1/50000 is divided into the noise filed,regional geological background field and local anomaly and good application effect is obtained for extracting the weak information of deep-buried uranium deposits. |
| Keywords: | granite-hosted uranium deposits geochemistry field of uranium fractal singular value decomposition |
