oceanic tholeiite

On the basis of quantity calculation of petrochemistry data and from the judge of distributed model of rare-earth elements, these, rocks mainly belong to the oceanic tholeiite series and a part belongs to the lime-alkali series.

根据大量岩石化学分析结果及稀土元素配分模式判断，大部分属大洋拉斑玄武岩系列，部分为钙碱玄武岩系列。

The REE of breccia biotite schist represents feature of oceanic tholeiite.

角砾状黑云母片岩的REE具有洋脊拉斑玄武岩特征；

Association of continental alkaline basalt with oceanic tholeiite and oceanic island basalt in the junction is reasonably interpreted.

较合理地解释了结合带内，大洋拉斑玄武岩、洋岛玄武岩、大陆碱性玄武岩共存的地质特征。

The basalt in the south zone belongs to tholeiite series, enriched in all the trace elements and REE except Y, Yb, Sc and Cr, showing its characteristics are consistent with those of oceanic tholeiite.

南带玄武岩除Y、Yb、Sc、Cr外，其他均富集，显示与大洋拉斑玄武岩曲线一致。
