| 摘 要： | 根据层序地层学的基本原理,综合利用露头、钻井、测井和地震等资料,建立汤原断陷古近系层序地层格架,识别出2个超层序、11个三级层序。运用体系域四分法在断陷两侧三级层序内同一体系域内识别出了相近的沉积体系。汤原断陷古近系主要发育扇三角洲湖底扇、扇三角洲半深湖、扇三角洲湖底扇半深湖、扇三角洲滨浅湖半深湖和扇三角洲滨浅湖体系。

| Abstract: | The sequence framework of Tangyuan fault depression is divided into 2 supersequence sets and 11 third-order sequences in Paleocene according to the theory of sequence stratigraphy,natural outcrop,and data of drilling,logging and seism.Similar depositional systems are recognized in the same system tracts of the third-order sequences at both sides of the fault depression by the terminology of four-division scheme.The Tangyuan fault depression of Paleocene mainly developed the system of fan delta-sublacustrine fan,fan delta-sub-deep lake,fan delta-sublacustrine fan-sub-deep lake,fan delta-shore lake-sub-deep lake and fan delta-shore lake. |
