Embodiment 1

[0016] Such as figure 1 As shown, the embodiment of the present invention provides a kind of metallogenic prediction method, comprising:

[0017] Step 101 , sampling the whole hole from the surface to the ground in the mining area to be explored according to the preset interval to obtain a group of sampling samples.

[0018] In this example, in order to better use the fluid inclusions in the mining area to be investigated to guide ore prospecting, the selected sampling objects should be minerals that are ubiquitous, stable in physical properties, stable in grains, and well-developed in crystal form. At this time, step 101 includes: selecting quartz, calcite, fluorite, dolomite or barite from the mining area to be explored as the sampling object; sampling the sampling object from the surface to the underground according to the preset interval to obtain a set of sampling objects. sample.

[0019] In this embodiment, the weight of the sampling sample obtained by performing full...

Abstract

The invention discloses a metallogenic prediction method, relates to the field of mineral resource exploration, and aims at solving a problem of low accuracy of metallogenic prediction. The method comprises the steps that S10, complete hole sampling is performed in a mining area to be explored from the surface to the underground according to the preset distance so that a set of samples are obtained; S20, the three-dimensional space position of each sample in one set of the samples is acquired; S30, main metallogenic elements of all the samples and fluid inclusion parameters of each sample are respectively confirmed; S40, interpolation is performed on the main metallogenic elements by adopting a three-dimensional distance inverse weighting method according to the three-dimensional space position of each sample so that a three-dimensional space distribution model of the main metallogenic elements is obtained; S50, interpolation is performed on the fluid inclusion parameters by adopting the three-dimensional distance inverse weighting method according to the three-dimensional space position of each sample so that a three-dimensional space distribution model of the fluid inclusion parameters is obtained; S60, and the mineral exploration direction of the main metallogenic elements is confirmed according to the three-dimensional space distribution models of the main metallogenic elements and the fluid inclusion parameters.

Description

technical field [0001] The invention relates to the field of mineral resource exploration, in particular to a metallogenic prediction method. Background technique [0002] The traditional two-dimensional prospecting method is based on the metallogenic prediction theory, combined with surface geophysics, geochemistry and prospecting engineering data, to explore the spatial geometry and scale of mineral resources. [0003] However, the ore deposit is not flat, it is a geological body with special significance existing in three-dimensional space; the essence of the traditional two-dimensional prospecting method is to extract the three-dimensional mineralization information superimposed on the two-dimensional plane. It is inevitable that information will be distorted or lost, resulting in a low accuracy rate of metallogenic prediction. Contents of the invention [0004] The invention provides a metallogenic prediction method, which can improve the accuracy of the metallogenic...
