文章题目：Contrasting collision-induced far-field orogenesis controlled by thermo-rheological properties of the composite terrane
文章摘要：The continental collision-induced far-field intraplate deformation may be topographically separated from or coherent with the collision front, the mechanism of which is poorly constrained. Here, we build a series of 2D thermo–mechanical models to explore the controlling factors of distal orogenesis in the framework of a composite terrane sandwiched between two strong continental blocks. The model results suggest that the development of distal orogenesis requires a strong rheological heterogeneity in the overriding lithosphere. Two types of far-field collisional effects with distinct patterns of topographic evolution are identified, characterized by (I) a delayed and discrete distal orogenesis separated from the collision front by a low-relief, less-deformed terrane interior, and (II) an instant distal orogenesis subsequently integrated into a progressively growing plateau. These two types of far-field orogenesis are revealed to be analogous to the development of the Kopet Dagh and northern Tibet. The comparisons between model results and geological observations provide significant constraints on the dynamics of crustal-scale deformation propagation and the formation of distinct lithospheric architectures.
