| Abstract: | The Chundu porphyry copper deposit is a new deposit discovered in recent years, which ore bodies hosted in the granodioritic porphyry, contact zone between rock body and its wall rock. Based on the geological feature, isotopic geochemistry of the Chundu porphyry copper deposit has been studied in this paper. The results show that the δ34S composition of the Chundu copper deposit similar to the mantle, and the sulfur is mainly derived from the magma with a small amount of crustal sediments. The composition of lead isotope with a characteristic of mixed was mainly from upper mantle and lower crust. The ore-forming fluid of the deposit mainly derived from magmatic water and partly from atmospheric water, which is similar to most of porphyry copper deposit. |
