Abstract:

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.

Key words: basin prototype, superimposition, Dabie orogenic belt, Tancheng-Lujiang fracture zone, southern North China
