| Abstract: | The anomaly threshold of geochemistry element is one of important problems of geochemistry research.The traditional method only thinks about the randomness of data.However,the self-similarity and randomness are poor considered.In this study,the anomaly thresholds of geochemistry element are studied using content-area of fractal theory.The results between this study and traditional method show this method has more theory basis and practicality and the recognition accuracy of geochemical anomaly can be improved greatly. |
