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砂砾岩体具有"平面分带、垂向分期、持续后退、继承性强"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”育模式为：从晚侏罗到白垩纪末期育“盆地”开始、展到早第三纪断陷湖盆育、再演化为晚第三纪及第四纪地陷育阶段。
