Problems solved by technology

[0004] The application of hyperspectral technology in my country is in its infancy, and there are few applications. The research done is not yet comprehensive, and it has not yet been promoted and produced on a large scale.
In addition, during the sample test, some external factors will affect the measurement results, resulting in errors in the measurement
Moreover, the cost of sample analysis is relatively high. The more altered minerals are analyzed, the more time is required and the higher the cost.

Abstract

The invention discloses a hydrothermal deposit prospecting method and system based on white mica wavelength change. The method comprises the following steps: acquiring spectral reflection data, drawing a characteristic curve based on the spectral reflection data, performing multi-peak analysis on the characteristic curve to obtain a characteristic absorption peak, and performing multi-peak fitting on the characteristic absorption peak to obtain a characteristic wave peak; and performing parameter calculation on the characteristic wave crest to obtain characteristic wave crest parameter data, and analyzing the characteristic wave crest parameter data to obtain a prospecting result. The method is simple and easy to implement, short in analysis time and capable of rapidly completing data measurement, analysis and application, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mineral exploration, in particular to a hydrothermal deposit prospecting method and system based on muscovite wavelength variation. Background technique [0002] The formation of hydrothermal deposits is a complicated process with many influencing factors. In most deposits, the alteration is intense and complex, and the extent of alteration is widely distributed. However, alteration information is an important basis for ore prospecting. The surrounding rocks of ore deposits are altered and developed, and the altered rocks formed are important signs of ore prospecting, which are closely related to mineralization. As a rock-forming mineral, muscovite in surface rocks is also an important alteration mineral in the sericization zone of hydrothermal deposits, and is closely related to mineralization. Sericite is an important altered mineral in the sericization zone under the porphyry system. From the perspec...
