基于云模型的三維原生暈地球化學(xué)空間分布研究
[Abstract]:In prospecting practice, geochemical exploration data is an important source of information. One of the objectives of geochemical data processing is to obtain from a large number of observational data, in the case of complex relationships, Useful information is extracted from geochemical raw data by mathematical method to reveal the intrinsic relationship between indicator variables (mainly chemical elements) and various geological phenomena. It provides method and technology for prospecting geochemical prospecting mineral resources and solving geological problems. Cloud model is a qualitative and quantitative interchangeability model designed by Li Deyi academicians in 1990's. On the basis of the classical fuzzy set method and probability theory, the model combines fuzziness and randomness effectively with the help of numerical features to complete the mutual transformation between quantitative values and natural language uncertainties. Cloud model has been widely used in many fields, such as association rules, data mining, spatial uncertainty query, uncertainty reasoning and so on. With the development of knowledge, cloud model has become a powerful tool to transform quantitative information and qualitative concepts. The study on the spatial distribution of geochemical elements in primary halo is the core of exploration geochemistry, and it is one of the important ways to reveal the spatial enrichment and variation of geochemical elements. The geochemical data of primary halo are uncertain in sampling and analysis, and the distribution of elements in the crust is regional randomness and inhomogeneity. The data of primary halo geochemistry elements are processed by cloud model, and the spatial properties of geochemical data are studied in space, and the spatial distribution of primary halo geo-chemical elements is analyzed. The main work of this paper is to study the spatial distribution of geochemical elements in the primary halo based on cloud model. The study area is selected from the copper-gold ore area of Jiguanzui in Daye, Hubei Province. The research object is geochemical analysis data of primary halo in boreholes. The purpose of this paper is to obtain the digital eigenvalues through the reverse cloud generator, and then apply the digital eigenvalues to the forward cloud generator to obtain a series of cloud droplets. The weak peripheral data are weakened by the 3En rule of the cloud, and the backbone basic data is highlighted. The reverse guide back to the spatial data format, through geochemical maps, combined with the actual geological conditions, shows that the cloud model is feasible in dealing with the primary halo geo-chemical element data, and has obvious effect on the late metallogenic prediction.
