Abstract In this study,the authors tried to carry out metallic active state prospecting test of the Chengmenshan copper polymetallic deposit along the lower Yangtze reaches metallogenic belt. The results show that, in the Chengmenshan ore district within the humid mountain landscape, Au mainly exists as organic Au, and Cu exists as organic Cu and Fe-Mn oxides. Above the ore body,the rate of active state reachs more than 30%, which can fairly effectively reflect deep mineralization information. This method can locate the concealed deposit. Organic Au and Cu can well reflect latent mineralization information. The Lianmeng silver-gold mineralization spot was found by using this method in southern Chengmenshan in the subsequent soil survey.
