摘要
The Bangpu molybdenum-copper deposit in Tibet,which is located in the eastern part of the Gangdise porphyry copper belt,is a large-scale porphyry deposit,dominated by Mo and Cu with associated Pb-Zn.Sulfur and lead isotopic studies show that it shares typical magmatic sulfur characteristics(δ34S=0‰).Lead isotopes indicates its normal lead characteristics with the same homologous evolutionary history or the same source.The eigenvalue and lead isotopic diagram show that they are characterized by mixed crustal and mantle materials,dominated by crust origin,probably originated from the upper crust involving orogeny.
