摘要
秦皇岛柳江盆地二叠系包括山西组(P1s)、下石盒子组(P1x)、上石盒子组(P2s)、石千峰组(P2sh),岩性主要为灰黑色中细粒长石岩屑杂砂岩、黄褐色-灰白色含砾粗粒长石岩屑砂岩和紫红色中粗-中细含砾砂岩,通过对本区二叠系地层特征的研究,得出二叠纪沉积环境逐渐由宽广的沿海滨岸成煤沼泽环境的海陆交互相转变为内陆盆地的大陆河湖相沉积。
The Permian of the Liujiang Basin in Qinhuangdao includes the Shanxi Formation (P1s), the Lower Shihezi Formation (P1x), the Upper Shihezi Formation (P2s), and the Shiqianfeng Formation (P2sh). The lithology is mainly grayblack medium-fine feldspar lithic sandstone, yellow-brown-grey-white pebbly coarse-grained feldspar lithic sandstone and purple-red medium-fine-fine pebbly sandstone. Based on the study of the Permian strata characteristics in this area, it is concluded that the Permian sedimentary environment has gradually changed from a broad ocean-land interaction phase along the coastal coal-forming marsh environment to a continental river lacustrine deposit in the inland basin.
