摘要
根据地震、测井、岩芯资料 ,探索了汤原断陷的层序地层学特征。在汤原断陷下第三系共划分 1个Ⅰ级层序、4个Ⅱ级层序和 2 0个Ⅲ级层序 ,并建立了断陷的层序地层格架。此外 ,结合区域构造特征 ,探讨了汤原断陷的充填史 。
Based on the date analysis of seismic, logging and core, the feature of sequence stratigraphy in Tangyuan fault-depression is probed in this paper. One Ⅰ grade sequence, four Ⅱ grade sequence and twenty Ⅲ grade sequence are divided in this fault-depression, therefore the new sequence stratigraphic framework of Paleogene in Tangyuan fault-depression is established. In addition, according to regional tectonic feature the filling history of Tangyuan fault-depression is reconstructed. It is believed that the differential movement of boundary faults are the key factor for the Paleogene sedimentation of Tangyuan fault-depression.
