The Mesozoic stratigraphic architecture of the eastern Yihezhuang Salient, Jiyang Depression

摘要

In Mesozoic eastern North China Block, there happened severe geotectonic transformation, which led the formation of complex Mesozoic complex stratigraphic architecture. In this study, eastern Yihezhuang Salient in Jiyang Depression was taken as an example to study the complex stratigraphic architecture based on recognizing the Mesozoic tectonic unconformities in order to help research the geotectonic transformation. According to boreholes, well logs and seismic profiles, Tg. Tgm and Tr were recognized through the AC-DEPTH relationship curves and unconformable contacts in seismic profiles, and finally the stratigraphic architecture were established.
