| 摘 要： | 黄县早第三纪断陷盆地充填沉积序列共划分出三个层序(三级层序),层序Ⅰ不完整,层序Ⅰ和层序Ⅱ皆由低位体系域、扩张体系域和萎缩体系域三个基本单位构成。层序界面主要有区域构造运动界面和盆地构造应力转换面一体系域转换界面两种类型。聚煤作用、油气聚集主要发生在盆地低水位至扩张期,低水位和扩张体系域含有主要的煤层和油气母岩(生油岩)。

| Abstract: | Three sequences(third-order sequence)can be distinguished for the Huangxian Paleo-gene fault basin.Sequence I is interrupted.Both Sequences Ⅱ and Ⅲare composed of three basic units:lowstand systems tract(LST),expanding systems tract(EST)and reducing systems tract(RST).There are two kinds of sequence boundary:regional tectonic plane and basin tectonic stress transform plane-systems tract transform plane.Coal and oil accu-mulation took place mainly in the lowstand to expanding periods,and thus coal seams and parent strata of oil and gas(oil-generating strata)are hosted dominantly in the lowstand and expanding systems tracts. |

| Keywords: | fault basin sequence division expanding systems tract basin-filling sequence Huangxian Basin Shandong |
