| 英文摘要 | The complex body in Liangtun-Kuangdongguo, Liaoning Province, China, mainly consists of alkaline rocks such as pyroxene syenite, aegirite-augite syenite and aegirite-augite-hornblende syenite. According to the previous whole rock Rb-Sr isochron age data of 1866+/-115Ma with I-Sr=0.7049, it is the oldest alkaline syenite reported in China up to now. The data of Zircon U-Pb and whole rock Sm-Nd data reported in this paper show that the complex body has a U-Pb isotopic age of 1857+/-20Ma, and a whole rock Sm-Nd isochron age of 1787+/-180Ma, with a epsilon(Nd)(t) value between -4.8 and -5.0. This means that the complex originated from enriched mantle material, with the upper limit age of 1857+/-20Ma. So the authors suggest that during early Proterozoic era an enriched mantle reservoir existed in the North China platform, and the main part of the Liaohe Group was formed before 1900Ma. |
