Coupling and Mass Exchanging in Foreland-thrust Systems

As typical representatives of convergent-type basins, foreland basins subside due to compressive flexural tectonics and, dynamic subducted slabs, as well as various gravitational loads. Events observed in foreland-thrust coupling are corresponding or symmetrical phenomena phenomenon such as orogen rising and basin subsiding, orogen advancing and basin migrating, orogeny ending and basin overfilling, and rhythmic/or cyclic transfusion transfer etc.. Dominated radically by entire dynamics and kinematics in convergence belts, mass exchange during foreland-thrust coupling are represented by clast transfusion transfer from orogen to basin and brittle faults in superficial layers, and heterogeneous ductile flow of multimode and multidirection in deep layers. Both foreland basins and adjacent orogens are resulted from the entire regional dynamics with complicated direct or indirect interactions.
