| 摘 要： | 文章从温都尔庙群岩石组合、岩石化学和同位素年龄特征入手,研究显示该套岩石具有洋中脊拉斑玄武岩的特征;岩石稀土特征表明其形成于陆间小洋盆环境.它属于华北板块北缘中段新元古代构造演化阶段的产物,为研究华北板块北缘地壳演化提供了新的依据.

| Abstract: | Study on rock assemblage,petrochemistry and isotopic age of Ondorsum Group shows that this rock assemblage is characteristic of ORB and the REE pattern reflects a small inter-continent basin sedimentary environment.The assemblage is the product of Neo-proterozoic tectonic evolution at middle of north margin of north China plate and provides a new basis for the study of crustal evolution of North China plate. |

| Keywords: | Ondorsum group oceanic crust reics Neo-proterozoic era north China plate Baiyun′ebo |
