Study on the mechanism of remote sensing anomaly extraction and correlation analysis of ore controlling: Take the Qimantag metallogenic belt of Qinghai as an example
Abstract
Information extraction from remote sensing and the research of ore controlling factors has been in the two aspects isolated corrosion, the relationship between remote sensing anomaly extraction and deposit metasomatic alteration in the theory system has not yet been discussed. Combing the mineralization clues and altered minerals has discovered of Qimantag metallogenic belt according to the geological background of the work area, the paper has established the relationship of main alteration mineral-deposit genetic type-deposit type-type of remote sensing data and the geological and physical model through analyzing the relationship between the corresponding alteration characteristics of multi-source remote sensing data and spectral diagnosis mineral band. The combination analysis of remote sensing alteration information distribution and ore controlling factors of study areas, such as basic deposit types, stratigraphic and structural improved the correlation analysis method of remote sensing anomaly information and ore controlling ore and delineated the remote sensing anomaly packet, it has important significance for the 2D regional metallogenic prediction.
