Abstract: Analyzed the association characteristics of geochemical elements using independent component analysis（ICA）.The new concept of combining nonlinear science with information technology in geochemical data processing is put forward. Through the application research of stream sediment survey material in Rire area，prove that the FastICA for the geochemical elements association calculating is effective.

Key words: Blind source separation, Independent component analysis, Ore-forming elements association
