摘要: Abstract The Daloushan mountain chain, located in the centre of upper Yangtze continental block, is considered to represent locus tectonic shortening resulting from eastward growth Tibetan Plateau and NW-thrusting Xuefeng Orogen. Structural data apatite fission-track ages have been used decipher geometry kinematic evolution Daloushan. latter subdivided into two domains: eastern domain, governed by west- NW-verging thrusting deformation with dextral transpression, a western south-verging deformation. Both domains experienced four episodes deformation, synchronous stages post-Cretaceous denudation, marked rapid cooling propagating 20 5 Ma, at rate ∼0.1 mm/year. In particular, last denudation are closely related Plateau. This indicates an intra-continental transfer forcing Palaeo-Pacific Tethys-Himalayan Tectonic Domain across
