    STRATIGRAPHIC SEQUENCE OF TUCHENGZI FORMATION IN JINLINGSI-YANGSHAN BASIN, WESTERN LIAONING PROVINCE

      摘要
    • 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.
