粤北刘家山地区多元素分形维数谱函数及其对矿化的指示分析
Fractal Dimension Spectrum Function of Multielements of North Guangdong and Its Mineralization Instructions
摘要
Abstract
In order to study the influence of distribution of geochemical elements on mineralization, this study uses Q-Q plot and cluster analysis to discuss the space distribution of elements in Liujiashan of northern Guangdong province. 12 elements related to mineralization were analyzed on 1573 drainage sediment samples from Liujiashan to recognize their fractal distribution. In contrast to traditional anomaly recognition method with iterative mean ± σ, this paper uses C-A fractal to separate anomalies from their background values, and calculates multifractal spectrum function. The C-A fractal analysis unites element content and frequency distribution of statistic method and singularity space configuration. It is useful for distinguishing chemical background and anomalous values which are relate to mineralization, and can provide significant clue for mineral potential evaluation.关键词
