Eogene

As an example,the 3 D paleostructure of the boundary between Middle Eogene an...

作为实例，我们重建汤原断陷早第三纪中期白垩系顶界三维古构造。

In eastern China, transgression occured periodically during Eogene, and formed specially paleobio-cenosis,mineral association and rock type.

在中国东部早第三纪化过程中曾周期性发生过海侵,从而形有海相特征的岩石类型、古生物组合。

The basin tectonic model: it is intermont basin during late Jurassic to early Cretaceous, developed into faulted-lacustrine basin in Eogene, and evolved into depression in Neogene and Quaternary.

“盆”构造发育模式为：从晚侏罗世到白垩纪末期发育的山间“盆”开始、发展到早第三纪断陷湖盆的发育、再化为晚第三纪及第四纪陷发育阶段。
