Content-frequency fractal analysis based on geochemical data with different scales and media:A case study of the Dabaoshan copper polymetallic orefield in Guangdong Province
摘要
Abstract
In this paper, a comparative analysis of content⁃frequency fractal method was conducted for multi⁃range, multi⁃scale and multi⁃media geochemical field in the Dabaoshan orefield, It is proposed that the ore⁃forming elements with different dimensions and media basically show the same complex multifractal features, which is the necessary condition for elements to form the large⁃scale min⁃eral deposit, but not a sufficient condition. The authors hold that the proportion of local anomaly number of samples accounting for all of the samples of ore⁃forming elements will be exclusively more than 2% reflected in the multi medium⁃scale data, the proportion is repre⁃sented by the turning point of the value of continuous multi fractal dimension decrease, but the proportion of the value of elements with⁃out causing mineralization may be by far less than 1%. Fitting accuracy significantly influences the understanding of the type and prop⁃erties of the content⁃frequency fractal curve.关键词
