| 摘 要： | 通过辽北早白垩世泉头组地层研究,提出泉头组沉积层序划分方案:划分为2个层序,11个旋回层序,20个基本层序;总结了层序划分的4种类型及其识别标志;识别出3种沉积体系———湖相三角洲分流河道沉积体系、浅湖相沉积体系、湖相三角洲前缘沉积体系。

| Abstract: | After a study of the strata of the Early Cretaceous Quantou Formation in northern Liaoning,the authors propose a classification scheme of the depositional sequences of the Quantou Formation:two sequences,11cyclic sequences and20essential sequences,summarize four types of sequence classification and their criteria for recognition and recognize three sedimentary systems ,i.e.the lacustrine-deltaic dis-tributive channel sedimenta ry system,shallow-lacustrine sedimentary system and lake delta front sedimentary system. |

| Keywords: | Quantou Formation cyclic sequence essential sequence sequence sedimentary system Changtu basin |
