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.
