Reconstructing the Late Palaeozoic – Mesozoic topographic evolution of the Chinese Tian Shan: available data and remaining uncertainties

摘要: The topographic evolution of continents and especially the growth dismembering mountain ranges plays a major role in tectonic orogenic systems, as well regional or global climate changes. A large number studies have concentrated on description, quantification dating relief building active ranges. However, deciphering continental area submitted to recurrent deformation over several hundred millions years remains challenge. Here we present synthesis tectonic, geochronological sedimentological data available intracontinental Tian Shan Range describe its general from Late Palaeozoic Early Tertiary. We show that this has occurred two very distinct geodynamic settings, initiating during Carboniferous an ocean subduction - continent collision context before becoming, Permian, purely intra-continental. most Mesozoic, topography is mostly characterized by progressive decrease relief. Nonetheless localized, induced formation small-scale reliefs period. These deformations were driven far field effects possibly processes way still be fully understood.
