The tectonic effect by foreland basin system might not be significant since Kueichulin Formation corresponded to eustatic sea level change and the Kueichulin Formation might means an unaffected tecton - sediemntary unit. The locality might be the hinge of forebulge flex.

前凸起的运动模式应为以垂直向上抬升为主，而非有向陆迁移之现象之外，而其发生时间应为6.5 - 5.6Ma；由於桂竹林层仍符合全球海水面变化，则其表示了一个在前陆盆地系统挠曲行为中一个较不被影响的构造单元，则此应为前凸起之枢纽带位置。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
