基于多重分形理论的地球化学场分解与元素组合研究--以铜山岭-祥霖铺地区为例
The application of multifractal theory to the decomposition of geochemical fields and the study of element association:A case study of Tongshanling-Xianglinpu area
摘要
Abstract
Located in southwest Hunan Province and at the center of Nanling metallogenic belt, the Tongshanling⁃Xianglinpu area, in which several W⁃Sn and Cu⁃polymetallic deposits have been found, has great potential for the prospecting. In this paper, the multifrac⁃tal theory, i.e., the model of singularity, was applied to the decomposition of geochemical fields, on the basis of the data of 1∶50 000 geochemical survey obtained in the study area. The representative elements Sn and Ag were analyzed in detail, with good results a⁃chieved:the singularity reduced the influence of the high background value of rock mass and the variety background levels and intensi⁃fied the anomalies in low⁃value background zone;the fractal density reduced the influence of the data noise effectively, and the anoma⁃lies became more clear. This paper discussed the characteristics of element association preliminarily, and pointed out that it�s better to make a comprehensive analysis in combination with the respective advantages of original data and singularity.关键词
