Three technical problems of unevenness, matrix and heterogeneous mineralization effects, are considered and successfully resolved. This new technique was applied to three sites of Au, Sn and Cu deposits (representing higher, medial and lower atomic number minerals) in different exploration stages in China and satisfactory results are obtained.
