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”构造发育模式为：从晚侏罗到白垩末期发育山间“盆地”开始、发展到早三断陷湖盆发育、再演化为晚三及地陷发育阶段。
