Abstract In order to promote the application of multi-fractal theory to remote sensing exploration, this paper takes the West Junggar Region as the study area to build fractal dimension spectra by analyzing the characteristics of the region and the remote sensing image. Combined with spectra, the authors completed the lithologic classification and pyrite alteration extraction of the region. And then mineral targets of the region was identified with the support of the existing statistical data of mines and expert’s experience and knowledge. Practice has proved that the appropriate prospecting model and criteria established on remote sensing images of fractal theory and spectral characteristics can satisfactorily supply decision support to regional mineral exploration.
