| 摘 要： | 周口坳陷早白垩世主要发育冲积扇相、河流相、湖泊相、扇三角洲相和三角洲相等类型，其中谭庄－沈丘凹陷沉积相带呈东西向狭长展布，是一个典型的断陷盆地．本文在讨论了湖盆的物源、古地形、古水流、水介质条件及古气候条件的基础上，提出了早白垩世时周口坳陷的沉积格局。

| Abstract: | The sedimentary factes types of alluvial fans,fluvial deposits,fan deltas and normal deltaic deposits prevail in the Lower Cretaceous strata in the Zhoukou depression in which the Tanzhuang-Shenqiu factes zone appears in a EW-oriented narrow form.The sedimentary framework of the Zhoukou depression during Early Cretaceous time has been ascertained on the basis of the study of provenances, palaeotopography, palaeocurrent,water media and palaeoclimates. |

| Keywords: | Tanzhuang- Shenqiu depression Early Cretaceous sedimentary facies sedimentary framework |
