Study On Geochemistry Of Primary Halo By Three-dimensional Multifractal Local Singularity Analysis

In the face of the problem of "difficult to find,difficult to identify and difficult to use",it is an inevitable trend to obtain resources for deep exploration.Weak new anomalies,complex superposition separation,deep fault and spatial displacement,and other new technologies and new methods that need urgent exploration of mineral resources.Fractal theory is a branch of mathematics which could characterize complex processes created by the American legal mathematician Mandelbrot in the 1970 s.Since 1975,fractal theory has been rapid development both in mathematics and in application.Due to the strong application of fractal geometry,it has made remarkable achievements in the application of various disciplines.Fractal theory and multifractal theory provide a new perspective to understand the metallogenic process.The local singularity theory based on multifractal has been widely used in mineral exploration at home and abroad.Geochemistry of primary halo is an effective means of deep geochemical exploration,geochemistry of primary halo is a conventional method of deep mineral forecast based on elemental basis sequence.This paper constructs a three-dimensional multifractal local singularity model based on the theory of multifractal local singularity.This article study the local singularity of three-dimensional geochemical elements by constructing three-dimensional data bodies,and then discover the spatial enrichment of elements,and provide geochemical support for deep mineral prediction.The copper and iron ore area of Tonglvshan in Daye,Hubei Province was selected as the research area.In this paper,three-dimensional modeling of the geological data of the geological body and borehole in the mining are a is carried out,and the three-dimensional multifractal local singularity analysis is carried out on the original halo-dimensional data body.First,the key parts is cut by the exploration line profile,research elements in the key parts of the enrichment characteristics,and then combined with the actual geological conditions,designated target location.The actual geological data of the mining area show that the predicted target position delineated by the three-dimensional multifractal local singularity analysis is in good agreement with the geological background.It has a reference significance.
