| 英文摘要 | Two kinds of granitoids with the similar geochemical characteristics outcrop in Qiaohuote copper deposit which lies on the north side of South Tianshan Suture Zone. The granodiorite outcropping on the south side of Qiaohuote copper deposit and the moylite occurring as an enclave in the volcanic rocks belong to I type granite. They both have calc-alkaline composition, and are characterized by enriched LILE and depleted HFSE and negative anomalies in Eu, Ta, Nb, and Ti. Tectonically, they are :related to the northward subduction of South Tianshan Ocean beneath the southern margin of Central Tianshan terrane. LA-ICP-MS zircon ages of 450.4 +/- 1.1Ma and 430.8 +/- 4.1Ma were obtained from these granitoids. The geochemical and age dating data reported in this paper indicate that these granitoids were formed in a subduction environment, the northward subduction of South Tianshan Ocean may start at Late Ordovician (450Ma) and still be active during Early Silurian (431Ma) in Qiaohuote region. The age of granodiorite is earlier than the ore-host volcanic rocks, therefore, the metallization of Qiaohute copper deposit is independent of the granodiorite. |
