| 英文摘要 | Granite porphyry in the Sangdewulan copper-molybdenum district in the Qiongheba area, East Junggar was characterized by the abundance of sanidine and quartz phenocrysts with intragranular fractures and fractured core zircons, which was formed in a pre-emplacement magma chamber. Zircon U-Pb dating results suggest that the fractured zircons formed at age of about 442. 2 +/- 3. 5Ma, and the rim zircons at about 412. 7 +/- 3. 3Ma. The age of about 413Ma shows the time of emplacement and crystallization of the granite porphyry. Hf isotopic data of zircons suggest that the fractured cores and rim had a similar value of epsilon(Hf) and t(DM2), and were most possibly derived from a same magma resources. This indicates that magmatic activity in the Qiongheba arc appeared at least from 442Ma in the Early-Paleozoic era. High epsilon(Hf)(t) value (10. 3 similar to 15. 1) and relative big model ages (t(DM2) =469 similar to 761Ma) suggest that magma formed granite porphyry in the Sangdewulan district were likely derived from the remelting of Late-Proterozoic-Ordovician basaltic crust. |
