The Tuchengzi Formation is widespread in the Yanshan intracontinental orogenic blet of North China, which is one of the most typical lithostratigraphy units clearly constrained by the low and upper boundaries. Base on the regional geological correlationship, our works show that Tuchengzi Formation's age and stratigraphy are much different from west to east in the Yanshan belt. In the western basin, Tiaojishan volcanic units is very rare or few, Tuchengzi Fm. including Jiulongshan deposits and Tiaojishan volcanic units and its age is Middle-Late Jurassic;on the contrary in the eastern basin Tuchengzi Fm. is same as its stratotype section and its age is Late Jurassic-Early Cretaceous, Tiaojishan volcanic units is rich and very widespread,. Fossils and Isotopic dating constrain the Tuchengzi Fm.range from 156 to 139 Ma, assigned to Late Jurassic-Early Cretaceous. The character of the asymmetric fillment, E-W distributions of sedimentary facies and paleocurrentwater indicate that the Tuchengzi stage deposition was controlled by synsedimentary thrusting on the north sides of the basins. The Late Jurassic Early Cretaceous basins were generated under the compressitine condition from the north to the south, belonging to the interior compressional volcanoic sedimentary basin in the intracontinental Yanshan orogenic belt.
