Abstract

The invention provides a geochemical data element sequence structure analysis method and device, and relates to the technical field of geochemical data processing. The method includes the steps: acquiring element measuring values of geochemical data of a geologic body, and preprocessing the element measuring values to generate unified dimensional element data; performing optimal ordering of a geochemical element for the unified dimensional element data by the aid of a first preset rule to generate an optimal sequence curve of the geochemical element (also known as an element gene spectrum curve); determining sequence structure characteristics of the geochemical element of the geologic body according to the optimal sequence curve of the geochemical element. Geochemical data are analyzed by the aid of information of multiple elements, association and combination information between multiple elements are considered, sequence element information of rock forming and ore forming under the geologic actions can be completely excavated, and systematization of geochemical action is taken into full consideration.

Description

technical field [0001] The invention relates to the technical field of geochemical data processing, in particular to a method and device for analyzing the element sequence structure of geochemical data. Background technique [0002] At present, the development of geochemical data processing and analysis (also known as data mining) is divided into two levels. The first level is the most basic single-element anomaly analysis (which can be called quantitative geochemistry). Add several times the standard deviation to determine the lower limit of the anomaly, and then draw the anomaly contour map of the single element. The lower limit of abnormality is generally based on the statistical parameters of single-element data, and then determined according to the experience of researchers, such as the mean plus 2.5 times the standard deviation. In recent years, fractal technology has been developed to determine the lower limit of anomalies. The single-element contour map can also be...
