DIVISION OF SEQUENCE STRATIGRAPHY OF PINGHU FORMATION IN XIHU SAG IN EAST CHINA SEA
-
摘要: 共识别出平湖组5个三级层序界面T36、T35(Sb1)、T34(Sb2)、T32(Sb3)、T30(Sb4)和3个体系域界面f1、T33(f2)、f3。平湖组共有6个段,可划分出3个沉积旋回。平湖六段未见底,沉积旋回性不清,平湖五段为SⅢ1,平湖四段和三段组成SⅢ2,平湖二段和一段划分为SⅢ3。本区短周期(四级层序)海平面变化曲线的包络线(相当于三级层序)和全球海平面三级周期的变化曲线基本一致,反映全球海平面变化对本区层序发育有明显的影响。Abstract: We have totally recognized five 3rd sequence boundaries,that is, T36,T35(Sb1),T34(Sb2),T32(Sb3)and T30(Sb4) and three systems tract boundaries f1, T33(f2) and f3. The Pinghu Formation has six sections, divided into three 3rd sequences. The Pinghu sixth section has not been seen to the bottom, and the depositional cycle are unclear. The Pinghu fifth section is SⅢ1, Pinghu fourth and third sections compose SⅢ2, and the Pinghu second and first sections are divided into SⅢ3. The envelope curve(equal to 3rd sequence) of the short-cycle sea level(4th sequence)is basically consistent with the 3rd cycle curve of the global sea level changes, reflecting that the global sea level change has obvious influence on the sequence growth in this zone.
