Based On Cloud Model Of 3D Primary Halos Geochemical Studies Spatial Distribution

In prospecting practice, exploration geochemistry data is an important information source, one of the goals of the geochemical data processing is using mathematical method to extract the useful information from a large number of observation data, and reveal the indicator variables(mainly chemical element) intrinsically linked with a variety of geological phenomena, look for mineral resources for exploration geochemistry and geological problems such as technical service method. This article focuses on introducing a new comprehensive geochemical anomaly extraction method and its application is a problem of.Cloud model is in the 90 s Li Deyi academician of design about the processing model of qualitative and quantitative exchange. The model on the basis of the classical fuzzy set method, probability method, in principle, with the aid of object features the fuzziness and randomness of several son for effective combination, thus successfully completed quantitative numerical and uncertainty of mutual transformation of natural language. Cloud model the application field is very broad, scholars have been its application to the association rules, uncertainty of data mining, spatial query, knowledge representation, uncertainty reasoning, etc. Another cloud model in a complex system effectiveness evaluation are more widely applied research. With the continuous development of knowledge, cloud model has become a quantitative information and qualitative concept transformation of powerful tools.Spatial distribution law of geochemical elements of primary halos research is the core of exploration geochemistry, it is to reveal the geochemical element enrichment of space and one of the important ways to change rule. Primary halos geochemical data uncertainty in sampling and analysis stage, the distribution of elements in the earth’s crust area the randomness and irregularity, combining with the 3 d modeling technology, using cloud model to deal with primary halos geochemical element data, and studies the geochemical data of space on the space property, analysis of the spatial distribution of geochemical elements of primary halos.In this paper, the main work is based on cloud model to study the spatial distribution of the geochemical elements of primary halos, the research area of hubei daye comb tsui copper gold mining area, geochemical analysis of the research object is the primary halos drilling data, the purpose is to data through reverse cloud generator, digital characteristic value, and then to use digital eigenvalue positive cloud generator, get a series of cloud droplets, weakening the weak peripheral data through the cloud of three rules, highlight key basic data, the wizard back to spatial data format, through geochemical map, in combination with the actual geological conditions, cloud model in the treatment of the primary halos on the geochemical element data is feasible, and has obvious effect for late metallogenic prediction.
