Flexural strike-slip basins

Abstract Strike-slip faults are classically associated with pull-apart basins where continental crust is thinned between two laterally offset fault segments. We propose a subsidence mechanism to explain the formation of new type basin no substantial segment or syn-strike-slip thinning observed. Such “flexural strike-slip basins” form due sediment load creating accommodation space by bending lithosphere. use two-way coupling geodynamic code ASPECT and surface-processes FastScape show that flexural emerge if deposited on thin lithosphere close fault. These conditions were met at Andaman Basin Central (Andaman Sea, Indian Ocean), seismic reflection data provide evidence extensive depocenter located parallel trace.
