Abstract: In the light of the modern concept of metallogenic series,the present paper presents a preliminary division of the metallogenic series and associations of different origins from magmatic intrusion,volcanism and sedimentation,respectively.Thirty-one lead-zinc deposits in the central and southern parts of the Nujiang-Lancangjiang-Jinshajiang metallogenic belt in southwestern China fall into three metallogenic series associations,nine metallogenic series and seven metallogenic subseries.The results of research are of importance to future exploration of the lead-zinc deposits in the study area.
