Digital image processing technique applied to geological exploration is presented in this paper. The data processed are involved with multi-geoscience information such as remote sensing

geology

geophysics

geochemistry and geography. To be directed against the particularity of geoscience information

various methods of digital image processing have been developed in order to enhance and extract the important information used in geological exploration and to assist in geotectonic structural analysis. The preliminary result has been achieved in mineral prediction

demonstrating the potential of digital image processing technology in geological exploration.
