Abstract

The invention discloses a rare metal prospecting method based on ground object hyperspectral remote sensing mineral combination zoning. The rare metal prospecting method comprises the following steps: step 1, acquiring remote sensing data; step 2, remote sensing data processing; step 3, remote sensing image generation; step 4, testing a ground spectrum; step 5, remote sensing anomaly extraction; step 6, filtering and screening; step 7, carrying out wave spectrum inversion; step 8, determining an ore deposit; according to the method, multiple absorption peaks of a ground feature spectral curve are determined through Gaussian multi-peak fitting, mineral combination information extraction is carried out, the inversion precision of ground feature spectral absorption characteristics on a remote sensing image can be improved, meanwhile, the ASD spectral curve of a real sample in a working area is compared with ASD spectral curves of different minerals in a USGS standard mineral library, the zoning features of different types of ore deposits can be obtained, interference factors and abnormal information are removed by performing abnormal screening and filtering on the remote sensing image, and the accuracy of the remote sensing image can be improved.

Description

technical field

[0001] The invention relates to the technical field of geological and mineral exploration, in particular to a rare metal ore prospecting method based on the zoning of ground features hyperspectral remote sensing mineral assemblages. Background technique

[0002] The remote sensing geological prospecting method is a method of prospecting using remote sensing information of geological bodies, using modern vehicles and instruments to detect the surface and near-surface geological bodies from a certain distance, so as to achieve the identification of geological bodies and geological phenomena and prospecting the goal of.

[0003] There are many methods of rare metal prospecting, and remote sensing prospecting is one of them, and its application is becoming more and more widespread. Remote sensing prospecting needs to bring the rock spectrum of the working area into the remote sensing image for inversion. However, the surface feature spectrum of a single mineral ...
