摘要:
提要:以板块构造学和层序地层学理论为指导思想,把苏北盆地古近纪划分为3个构造-层序,分别为古新世(TS1)、始新世(TS2)和渐新世(TS3)构造-层序。在此基础上,以构造-层序界面和最大洪泛面为界,以湖盆扩张体系域和湖盆收缩体系域为编图单元,编制了苏北盆地古近纪各地质时期的构造-层序岩相古地理图,探讨了各构造-层序岩相古地理特征及演化,为该地区油气勘探有利区块的预测和评价提供了更为可靠的依据。

Abstract:
Abstract:The Paleogene in the northern Jiangsu basin may be divided into three tectonic sequences in light of the plate tectonic theory and sequence stratigraphic theory; they are Paleocene(TS1), Eocene(TS2) and Oligocene (TS3). On that basis, maps of lithofacies and paleogeography of tectonic-sequences in various geologic epochs of the Paleogene in the Subei basin have been compiled with the tectonic-sequence boundaries and the maximum flooding surfaces as the boundaries and the lake basin lowstand systems tract and lake basin highstand systems tract as the map-making units, and the lithofacies and paleogeographic characteristics and evolution of various tectonic sequences have been studied. These provide a more reliable basis for the prediction and assessment of favorable areas for petroleum exploration in the Subei basin.
