Abstract The distribution of deposits is characterized by complexity and self-similarity.Fractal theory provides a new method for quantitative description of these character.At present, a single-fractal model is adopted by most researchers to obtain the capacity dimension of distribution of deposits with defferent scales.In view of the deficencies of the model, a multifractal model is introduced to the study of deposit distriution.The multifractal analysis has been worked on 29 large and medium scale deposits and total 75 deposits respectively based on a 1:2 000 000 distribution map of Au-Ag deposits of Hunan Province.The obtained multifractal spectrum is compared to the theoretic spectrum.The analysis shows good prospects for the Au-Ag deposit seaching in the provine.
