Mineral searching calibration method and system for element geochemical data screening

[0057] Embodiment 1: A method for ore-seeking calibration of elemental geochemical data screening, such as figure 1 As shown, it is specifically implemented by the following steps.

[0058] S101: Acquire the terrain altitude data of the target area, and divide the target area into multiple terrain areas of different terrain types according to the terrain altitude parameters and terrain altitude data; in this embodiment, the terrain types include mountains, plateaus, basins, and hills and plain.

[0059] The topographic area includes at least one independent topographic sub-area, and each topographic sub-area includes at least one collection area. The area calculation formula of the collection area is:

[0060]

[0061] Among them, S z Indicates the size of the collection area, S M Indicates the area size of the terrain sub-region, S 0 Indicates the preset area size, means S M with S 0 The ratio of is rounded up. It should be noted that if the terrain area is surrounde

[0072] Embodiment 2: An ore-seeking calibration system for elemental geochemical data screening, comprising:

[0073] The area division module is used to obtain the terrain elevation data of the target area, and divide the target area into a plurality of terrain areas with different terrain types according to the terrain altitude parameters and the terrain altitude data;

[0074] The data acquisition module is used to sample and collect elemental measurement data of target objects in the topographical area through the geochemical measurement method of water system sediments;

[0075] The data fitting module is used to obtain fitting element distribution information one-to-one corresponding to the terrain area after fitting the element measurement data of the target object by using the least squares square surface fitting method;

[0076] The data extrapolation module is used to use the inverse distance weighted average interpolation method to extrapolate and interpolate the fitte
