Based on apatite fission track (AFT), time-temperature thermal history and balanced cross-section, the authors conclude that the deformation evolution is progressive from southeast (Jiangnan-Xuefeng intra-continental orogeny) to northwest (Huayingshan thrust belt), and younger and younger. The results indicate that Mesozoic intra-continental deformation in western Hunan Province-Hubei Province to eastern Sichuan Province is progressive with a large width and a long diachronous interval. Because of the different basement, basement involvement level and participation level of detachment layer, the differences of shorterning and shortening rates reflect the obvious differences of intra-continental deformation and its dynamics.
