Abstract: The Biyuling copper depositis situated on the suture zone between Tarim-North China Plate and Kazakhstan Plate,which is related to the seaflo or hydrothermal activity during the intermission of the basic volcanic activity in the Middle Ordovician.The containing or erocks are jasper rocks,and they belong to the typical exhalative rock or hydrothermal sedimentary rock of containing iron cherts,which are the major productions in the period of the contemporaneous ore-forming.The mineral matters had occurred activated movement in the orogenic time,then the ore bodies enriched again in the crushed zones. So the distribution of ore bodies is controlled by the exhalative rock belts and the crushed zones.The jasper rock level and lithological character dominate the metallization of the disseminated and massive sulfides,and the ore bodies are controlled by the crushed zones;Intergrate the geological and element assem blage anomalies,we suggest that the propecting criteria is meta-volcanics,jasper rocks,Cu₂(CO₃)(OH)₂,limonite,CaSO₄ and element assem blage anomalies of Cu-Zn-Pb.
