1) Qiaotou sandstone
桥头砂岩
1.
Some different viewpoints on the origins of the Qiaotou sandstone in the Baode city of Shanxi Province.
对于山西保德地区桥头砂岩的成因,一直存在不同认识。
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。
