利用砂箱模型研究了增生楔与弧前盆地之间的复杂变形带。实验表明,盆地的演化是由一个主要的逆冲带,引起的速度不连续性本地化的尖端附近的刚性挡块。这种缩短是由向楔趾和主要逆冲带扩展的滑脱作用所调节的。这种稳定状态是由这两种结构之间的机械平衡驱动的。弧前盆地的沉积记录了这种相互作用
Analysis of sand-box models have been used to study the complex deformation zone between accretionary wedge and forearc basin. Experiments show that the evolution of the basin is controlled by a major backthrust zone, induced by the velocity discontinuity localized near the tip of the rigid backstop. The shortening is accommodated by the decollement spreading toward the toe of the wedge and the major backthrust zone. This steady state is driven by a mechanical balance between these 2 types of structures. The sedimentation in the forearc basin records this interaction
