| 摘 要： | 辽西金-羊（金岭寺-羊山）盆地土城子组为一套红色陆相碎屑岩组合.据其岩层垂向叠置规律及不整合面特征，可划分出3个Ⅲ级旋回层序，14个Ⅳ级旋回层序及各旋回层序所对应的冲积扇、滨湖、浅湖、最大湖泛面、风成沙漠沉积体系.这些沉积体系的有规律叠置，构成了土城子期3次湖扩张-湖萎缩沉积序列，其顶、底为明显的不整合面所界定.通过对旋回层序的划分和对比，建立了辽西金-羊盆地土城子组层序地层格架，从而揭示了中生代侏罗纪上统土城子组沉积期的盆地演化规律.

| Abstract: | The Tuchengzi formation in Jinlingsi-Yangshan basin,Western Liaoning Province is composed of a series of red continental detrital rocks.Stratigraphic sequence can be recognized by the vertical superimposition regularities of strata and the features of unconformity interfaces.Three Order III and 14 Order IV sequences of cycles are divided,as well as corresponding sedimentary system.The regular superimposition of the sedimentary system formed the sediment sequence of three cycles of lake expansion-contraction in Tuchengzi age.The top and bottom of the sequence are clearly bordered by unconformity surfaces.With the division and correlation of the sequence of cycles,a framework for the stratigraphic sequence of Tuchengzi formation in Jilingsi-Yangshan basin is established.This is a help to reveal the evolution of the basin in Tuchengzi age,Upper Jurassic,Mesozoic. |
