摘 要:Helium isotopic composition of inclusion fluid in pyrites from Machangqing copper deposit, China, has been measured. The measurements, with 3He/ 4He ratios ranging from 0 46-2 08 Ra, indicate that the helium in ore_forming fluid is a mixture of crust and mantle, and are consistent with the fact that the parental magma responsible for the formation of ore_forming fluid of the deposit is of crust_mantle provenance.
