| 本文主要从岩石组合、地质构造特征、原岩建造性质、岩石稀土元素的地球化学特征等论证了河北迁西三屯营和太平寨两个变质地体的存在及其形成演化规律。 |
| 英文摘要: |
| This article comments on the distribution, characteristics and evolution of two metamorphic terrains e.g. Sanyintuen and Taipingzai terrains, Qianxi, through the study on the rock assemblage, tectonic features, primary rock formation, volcanic rock series and REE geochemical features of Archean metamorphic series, with emphasis on REE geochemical features and their geological sense.Metavolcanics could be divided into three major series:tholeiite series, calc-alkali series and alkali series (and also komatite series?). Calc basalt in this area might be related to replacement of the mantle. |
