摘要
地球化学元素的异常下限值确定是地球化学中重要的问题之一,传统的方法只考虑了数据的随机性,对自相似性和不规则性数据则有所欠缺。采用含量-面积法来确定地球化学元素的异常下限,其结果和传统计算方法对比表明,该方法具有更好的理论基础和实用性,能有效的提高地球化学异常的识别精度。
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.
