本文论述了苏浙皖交界的二叠系栖霞期、茅口期和长兴期的纵横向沉积特征。提出了因古特提斯洋的扩张,陆壳内部受到引张,本区二叠系出现了一系列有规律的继承性拉张断陷槽沉积构造模式。

The paper discusses the lateral and vertical sedimentary features of the Pemian System developed during the stages of Qixia,Maokou and Changxing on the boundary of Jiangsu-Zhejiang-Anhui province. It is suggested that a series of sedimentary-structural models with regularity of successive extensionally faulted troughs occurred in the Permian System of the region due to the expansion of Paleo-Tethys sea and the extension undergone in the interior continental crust.
