The invention discloses a rapid metal mineral exploration and evaluation method. The method comprises a step of (A) remote sensing interpretation of regional structure framework: satellite remote sensing data such as Landsat TM / ETM, Worldview-2 and Aster are applied, digital image processing is carried out, a 1: 500,000-1: 25,0000 satellite remote sensing image map is made, linear and annular structure remote sensing interpretation is carried out with the key point of solving major basic geological problems related to mineralization, a remote sensing area structure framework is established, and a foundation is laid for research of area mineralization conditions and mineralization rules. According to the method, special multi-level remote sensing interpretation work is carried out for ore-forming / ore-controlling geological factors; aiming at the advantages of special remote sensing prospecting model research and the like on typical ore deposits and ore gathering areas, the problems thatspecial multi-level remote sensing interpretation work is not carried out on ore formation / control geological factors, and special remote sensing prospecting model research and the like are not carried out on the typical ore deposits and ore gathering areas are solved.

Description

technical field [0001] The invention relates to the technical field of geology and mineral resources, in particular to a rapid exploration and evaluation method for metal mineral resources. Background technique [0002] The evaluation and detection of mineral resources is more directly dependent on technological innovation. Through technological progress, a deep understanding of the mineralization process can be achieved, and the ability to find large-scale deposits can be enhanced. Therefore, new ideas and new methods of metal mineral prospecting and exploration are developing rapidly, such as the application of new technologies such as geophysical prospecting, geochemical prospecting, hyperspectral and high spatial resolution remote sensing, and digitalization, for the delineation of prospecting target areas and the location prediction of hidden ore bodies provide strong technical support. [0003] The traditional application of remote sensing to geological prospecting is...
