湖盆

Planar strips,vertical stages,continuous backpedal and strong succession are the characteristics of the glutinite body distribution in a rift extensional basin.

断陷伸展湖盆陡坡带上的砂砾岩体具有"分带、垂向分期、持续后退、继承性强"的分布特征。

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.

“盆地”构造发育模式：从侏罗到白垩纪末期发育的山间“盆地”开始、发展到早三纪断陷湖盆的发育、再演化三纪及四纪地陷发育阶段。
