摘要
The intrusive rocks in the Chundu porphyry copper deposit are mainly diorite porphyrite and granodioritic porphyry. The study on petrology and geochemistry of intrusive rocks indicates that intrusive rocks in the Chundu porphyry copper deposit are calc-alkaline series and formed in a tectonic environment of plate subduction. Trace elements are rich in large-ion elements such as Sr, K, Rb, Ba, Th and poor in Ta, Nb, P, Hf, Ti. Rare earth element distribution patterns show right slope, anomaly of δEu is not obvious, and δCe shows a slight negative anomaly.
