Abstract
The cupreous porphyries occurring in Shanyang District, Shanxi Province, were geotectonically developed in Qinling orogenic belt during Yenshan epoch. Their K/Na=0.84–2.74,δ = 2.48–3.70, DI = 70.19–80.69,δEu≈1,δ 34S is approximately consistent with that of the meterorite, lead isotope leadμ=9.03–9.42. All of the petrochemistry characteristics show that those porphyries are anatectic syntectic (I-type) granites formed in the intracontinental subduction belt, and the granites are favourable for forming the porphyry copper deposit.
