The matallogenic system and the prognosis,Dabaoshan Mo-Cu-Pb-Zn deposit,Guangdong province

The Dabaoshan polymetallic deposit containing aboundant copper,lesd and zinc mineral resouces.A significant process is that porphyry W-Mo mineralizaton system was discovered,with huge-scale prospective on top of the granite-porphyry,Iron deposit is weathering and leaching type one.Nonferrous metals mineralization is associated with magmatic hydrothermal process.It is established that the Daobaoshan porphyry metallogenic system,which granite porphyry is the ore-forming intrusion,Mo-W deposit occurred in the ore-forming center,with skarn-type Mo,vein-type Cu,Cu-Pb-Zn,Pb-Zn,Pb-Zn-Ag,and siderite veins gradually far away from this center.It is studied that the ore-forming depth and erosion level.The depth of the porphyry-type metallogenic system is more than 2000 meters,and that of erosion is more than 1500 meters(not includes that destroyed by fault).The important prospecting target shonld include three aspects: 1) Beyond the eastern boundary of the porphyry Mo mineralization system;2) the other side of the porphyry Mo deposit under the fault;3) NNW area of the porphyry,and porphyry type and skarn type Mo-W deposits around Chuandu intrusion.
