Abstract

The invention relates to a method for correcting regional geochemical data, comprising the steps of: collecting the analysis values ​​of each measurement element in the subregion and frame obtained through field geochemical sampling analysis, and systematically correcting the analysis value of each measurement element until drawing Until the geochemical contour map does not have the phenomenon that the contour line surrounds the boundary of the sub-area, the field sampling point data after a correction is obtained; at the spatial position of the known mineralization information, assign values ​​to each measurement element to form a virtual sampling point The data, based on the new sampling point data composed of field sampling point data and virtual sampling point data, is used for secondary correction until geochemical anomalies of relevant elements are displayed at all spatial locations of known mineralization information, and the data correction is completed. The method of the present invention performs secondary correction on the basis of the traditional correction method, so that the known mineralization information falls above the relevant element anomaly, and solves the problem of partial mismatch between the known mineralization information and the relevant geochemical element anomaly information .

Description

technical field [0001] The invention relates to the technical field of geochemistry, in particular to a method for correcting regional geochemical data. Background technique [0002] In the evaluation of regional mineral resource potential or comprehensive geological research, it often involves the splicing of geochemical measurement data of different maps or adjacent areas. These data are often completed by different periods, different batches, different laboratories, and different units, and there are often comprehensive systematic errors. If different batches of data are combined into a graph, it is easy to cause the contour line to surround the boundary of the data range on the graph, which makes it difficult to reasonably divide the background and anomalies. In this regard, the industry has proposed error correction methods for geochemical multi-map systems such as contrast method, partition standardization method, frame standardization method, adjustment method, and n...
