The Late Jurassic-Early Cretaceous volcanic rocks in Dabie orogenic belt are alkali rocks with high potassium content. The corresponding tectonic setting was not a subduction zone

but had certain relationship to plate subduction. The Tancheng-Lujiang fracture zone was characterized by its intenso-wrench or dextral strike-slip movement during Late Jurassic-Early Cretaceous. The Meso-Cenozoic basins in southern North China have significant differences

due to their specific tectonic settings. Taking Pingyu-Bangbu uplift as a boundary

the southern basins

located in the thrust front of Dabie orogenic belt

such as Hefei-Xinyang basin

are triple overlapping basins

which are composed of foreland basin prototype as a result of compressional orogenesis

strike-slip basin prototype as a result of tenso-wrench movement

and extensional counter-inclined normal fault and strike-slip faulted basin prototype. While the northern basins

located in relatively stable landmass

are multiple overlapping basins

which are composed of compressional foreland basin-intracontinental depression prototype

strike-slip basin prototype

depression

transtensional and faulted basin prototype as a result of weak compression

and depression basin prototype as a result of mass subsidence.
