| 摘 要： | 运用磁性地层学研究岩石单元磁性特征，是一种有效的地层对比方法。上马剖面按地层序列磁性特征的分异把磁极性一致或极性反向频率大致相当的区段组合在一起，由此划分了３３个磁性地层极性带，３个极性亚超带，２个极性超带，可与国际标准磁极性年表对比。

| Abstract: | The application of magnetostratigraphy to study magnetic features of lithologic units has an effect upon stratigraphic correlation.According to magnetic polarity association, the Jurassic-Cretaceous strata in the Shangma stratigraphic section are divided into 33 magnetostratigraphic polarity zones, 3 sub-superzones and 2 superzones comparable with the international magnetic polarity scale. |
