Embodiment

[0025] Embodiment A method of predicting hidden ore deposits using the chemical composition data of a single nanoparticle:

[0026] 1) Collect samples to be inspected: select the mining area, select the appropriate sampling time and sampling location to collect the best natural samples, and the samples to be inspected include but are not limited to groundwater, soil solid gas, animals, plants, and fault gouges;

[0027] 2) making the natural sample collected in the field into a sample to be tested that can be directly used for testing;

[0028] 3) Using field emission electron probe technology to analyze a single nanoparticle in the test sample, and quantitatively analyze the elements in the nanoparticle;

[0029] 4) First use EDS (energy spectrum) to qualitatively analyze the single nanoparticle, determine the contained elements, and then use WDS (spectrum) to quantitatively analyze the single nanoparticle;

[0030] 5) Use the chemical composition data obtained through quali...

Abstract

The invention belongs to the technical field of geological survey, in particular to a method for predicting hidden ore deposits by using the chemical composition data of a single nanoparticle. The method includes the following steps: collecting the tested sample, preparing the tested sample into a test sample, analyzing a single nanoparticle in the test sample by using probe technology, and performing qualitative and quantitative analysis on the elements in the single nanoparticle, according to the analysis The resulting chemical composition data predict concealed deposits. Through the qualitative and quantitative analysis of the elements in the test samples, the hidden ore deposits can be predicted according to the obtained chemical composition data, which can realize a qualitative leap from semi-quantitative to quantitative for ore prospecting data, and obtain more accurate and richer information about hidden ore bodies. Information, reduce the cost of prospecting.

Description

technical field [0001] The invention belongs to the technical field of geological survey, in particular to a method for predicting hidden ore deposits by using the chemical composition data of a single nanoparticle. Background technique [0002] With the rapid development of social economy, the existing surface resources can no longer meet the development needs of the national economy. In order to meet the rapid development of the economy's demand for mineral resources, it is urgent to carry out the exploration of deep hidden ore bodies. The characteristics of large burial depth and few outcrops have brought many difficulties to the prospecting work, especially in some areas with thick overburden. [0003] Geophysics and geochemistry are commonly used methods for prospecting. Geophysical prospecting methods cannot directly obtain information on mineralization anomalies. The element anomalies based on geochemical prospecting methods can have various background reasons. The da...
