| 英文摘要 | Zircon la-icp-ms u-pb dating of the fuyun adakites of turanggekuduke group, north xinjiang has been carried out in this study. the tuoranggekuduke group was previously considered to be early devonian. our result indicates that the zircon u-pb age of the fuyun adakites is 441.3 +/- 1.8ma. they might be formed at early silurain. previous studies suggest that the formation of the adakites approximately represents the beginning of oceanic crust subduction. since the fuyun adakites were suggested to be derived from the partial melting of the newly subducted paleo-asian oceanic crust, our result indicates that the initiation of the paleo-asian ocean subduction in north xinjiang occured at early silurian. this is the first acccurately isotopic age for the intiation of the paleo-asian ocean subduction. |
