| 英文摘要 | In this study, we research the major, trace element and Sr-Nd isotopic characteristics of volcanic host rocks, mineralized rocks, and ores of Qiaohuote copper deposit located in the Southeast of Yili block, Western Tianshan Mountains. We also conducted in situ zircon U-Pb LA-ICP-MS dating of the diabase, which intruded into the volcanic host rocks of Qiaohuote copper deposit. It is inferred that the volcanic rocks which are mostly composed of calc-alkaline andesitic volcanic rocks are interpreted as the derivatives of a mantle source modified by subduction zone fluids derived from the northward subducted Southern Tianshan oceanic slab in an island back-arc extensional environment. Laser ablation-ICPMS (LA-ICPMS) U-Pb zircon ages of 281.0 +/- 1.9Ma were obtained for diabase. The data presented here in conjunction with previously published data suggest that it was an island arc environment as the northward subduction of Southern Tianshan Ocean during Ordovician or even earlier in Qiaohuote region, and I-type granodiorite formed during Late Ordovician(ca. 450Ma). The host rocks of Qiaohuote deposit formed by the persistent subduction of Southern Tianshan Ocean during Middle-Late Silurian (ca. 430Ma), and meanwhile the volcanic exhalation-sedimentation, which was contemporaneous with the submarine volcanic rocks, produced the primary mineralization of the Qiaohuote copper deposit. Afterward,the ore bodies and host rocks were reworked and overprinted intensively by structures corresponding with the overall collisional orogenic process of the Western Tianshan during Late Carboniferous and Early Permian, the island arc crashed and fitted with the Central Tianshan block as then the diabase intruded into the host volcanic rocks (281Ma). The Qiaohuote copper deposit is a volcanic exhalation and sedimentation-structural reworking and overprinting type deposit, which formed by complicated processes involving the subduction and closing of Southern Tianshan Ocean and the accretionary orogenic process of Western Tianshan. |
