| 摘 要： | 河南永城地区的上古生界地层包括上石炭统太原组,下二叠统山西组、下石盒子组,上二叠统上石盒组、石千峰组,地层总厚度大于2000m,是在陆表海背景上发育起来的一套滨浅海及海陆交互相沉积。其中,太原组——山西组下段为浅海——潮坪体系沉积;山西组上段——上石盒子组为三角洲体系沉积;石千峰组是废弃三角洲平原上发育的滨岸沙丘体系沉积。尽管太原组、山西组及下石盒子组均有煤层发育,但山西组上、下段分界部位这一由浅海——潮坪体系转化为三角洲体系的特殊时期构成本区最有利的聚煤期。

| Abstract: | The Upper Paleozoic in Yongcheng area, more than 2000m thick, includes Upper Carboniferous Taiyuan Formation Shanxi and Xiashihezi Formation, Upper Permain Shangshihezi and Shiqianfeng Formation.lt is a set of shoreline and delta deposits developed in epicontinental sea background. The Taiyua Formation to the lower part of the Shanxi Formation is Submarian-tidal flat depositional system. The upper part of the Shanxi Formation to the Shangshihezi Formation is delta depositional system. The Shiqianfeng Formation is backshore-aeolian dunes depositional system. The seams were developed in the Taiyuan, Shanxi, and Xiashihezi formation. The middle part of the Shanxi Formation, as the transform section from the submarine-tidal flat depositional system to the deltaic depositional system, is the best coal-bearing part of the Paleoaoic in Yongcheng area. |
