Application of fractal theory to process Radioactive prospecting data

摘要

The distribution of radioactive geophysical and geochemical exploration data is very complex, it has multifractal characteristics, using the fractal theory to research conforms to the data distribution. The author selected some methods of fractal theory for study and compared with the traditional method, used content-area method to process gamma-spectrometric data of the carbonate-siliceous-pelitic type uranium deposit, it can reduced abnormal area and didn't omit ore occurrences, this will reduce the exploration workload; used fractal trend-surface method to process activated carbon radon measurement data of the sandstone-type uranium deposit, it can effectively strengthened the weak anomaly, and found new ore-generating anomaly area.
