Abstract:

Based on the research of distribution，lithologic feature of strata and regional tectonic evolution of remnant basins，prototype basin in Jurassic and Cretaceous in the Eastern North China are reconstructed.The researches show that in Early and Middle Jurassic，the Eastern North China was in the transitional period from Paleo-Asian system to Paleo-Pacific system，there were a series of small intermontane basins in the Bobai Bay area，sediments filled the depression formed by Indosinian thrust faults and gentle fold at the early stage and widely distributed at the late stage.From Late Jurassic to Early Cretaceous，tectonic and basin evolution were influenced by the Izanagi plate′s subduction to Asian continent.This Geotectonic transition led to the formation of large-scale rifts or faulted basins.Basin distribution and sediment filling were controlled by NW/NWW-trending and NE/NNE-trending fault systems.In Late Cretaceous，the areas to the west of the Tancheng-Lujiang fault zone were uplifted and denuded，with deposition of red fluvial-lacustrine sediments in a few basins.The remnant basins were the reflection of original sedimentation and late denudation.

Key words: remnant basin, prototype basin, basin evolution, Jurassic and Cretaceous, Eastern North China
