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

      Graphical Abstract
      • 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.
