| 摘 要： | 通过对滦平盆地沉积地层的野外观察，系统分析了九佛堂组的沉积特征及其变化规律，鉴别出特殊的岩石类型——熔积岩；较详细的描述了熔积岩所在剖面的沉积特征，最后结合盆地的区域地质背景，初步认为滦平盆地为火山—沉积盆地，强烈的同沉积构造运动伴随岩浆活动，致使盆地九佛堂组沉积地层内发育熔积岩。

| Abstract: | Based on observation in the field,this paper documents the sedimentary features and variations of Jiufotang Formation in the Luanping basin.A special kind of rock,namely,peperite,was identified and described in detail.Taking the geological setting of the basin into account,the author believes that the Luanping basin is a volcanic sedimentary basin.The intensive synsedimentary tectonic activity has resulted in the peperite in the Jiufotang Formation. |
