| 英文摘要 | There are hundreds of ophiolites blocks nearby the Kunzhong fault in the eastern Kunlun area. Ages of Sm-Nd whole rocks isochron for some ophiolites published are uncertain and formation ages of ophiolites have been debated. In this study, using whole rock and minerals isochron of cumulate gabbro from the Aqike ophiolites in the eastern Kunlun area in Xinjiang to determine the formation age of the ophiolites, the isochron of WR of gabbro, CPX and PLAG yields an age of 955 +/- 91(2sigma)Ma and epsilon(Nd) (t) = +0.4. It indicates that the Aqike ophiolite emplaced during the early Neoproterozoic, showing formation age of the Kunlun oceanic crust. Since then, it is possible that the Kunlun Paleoproterozoic terrane could be accreted to the south side of Tarim terrane with the Kunlun Ocean closed, which makes implication for tectonic simultaneity with assembly of the Rodinia supercontinent during period from 1.0 to 0.9 Ga. The evidence of the isotopic geochronology in this study is significant to discuss tectonic relationship of the Kunlun terrane and northwestern continent of China with Rodinia suppercontinent. |
