2.
This paper shows that it is possible that the sediment of low stand system tract can exist in the basin as the case of Qiaotou sandstone of the upper Taiyuan Formation interprets.
以太原组上部灰岩段中桥头砂岩为例 ,通过对露头、岩心、测井曲线的分析和层序对比以及海平面升降变化对研究区沉积影响的分析 ,认为桥头砂岩形成于不同的三级层序内 ,由 3套低位域下切河谷充填沉积叠置而成 ,说明在盆地内古大陆架上也可以发育低位体系域沉积。
3.
Tectonic disturbance,sea level change and differential compaction provided enough accommodation space for the distribution of K1 sandstone and Qiaotou sandstone.
本溪组—太原组形成于陆表海背景之下,陆表海基底平缓,层序结构大多为二元体系域结构,在构造变动、区域海平面下降及差异性压实作用等因素的控制下形成了以K1砂岩和桥头砂岩为代表的低位体系域河道下切充填。

桥头燕岩
补充资料：苍岩山桥楼殿
苍岩山桥楼殿：苍岩山位于今井陉县胡家滩附近。传说是隋朝南阳公主出家为尼的地方，是石家庄市的重要寺院山林。福庆寺是苍岩山的重要寺院，桥楼殿是福庆寺的主体建筑之一，建在一座长15米、宽9米的单孔拱券形石桥上。石桥飞跨在两悬崖绝壁之间，凌空飞架百米深涧之上，飘然欲飞，势若长虹。桥下石磴300余级，拾级而上可达桥楼殿。其建筑是一座九脊重檐楼阁式建筑，具有清代早期建筑特点，是我国建筑史上的奇迹之一。 现存桥楼殿是清朝康熙年间被火焚毁后重新修建的。
