在大陆碰撞的早期阶段，当大陆岩石圈经过长时间的正常大洋俯冲作用后发生俯冲时，俯冲岩石圈的温度分布和应力场的变化会导致岩石圈内部的破坏，并导致俯冲岩石圈深部的滑脱（板片滑脱或板片断裂）。我们使用一个二维时间相关的数值模型来识别控制板剥离的参数，并估计断裂深度和时间长度。俯冲大陆岩石圈的温度和流变性控制板片滑脱。
During the early stages of continental collision when continental lithosphere is subducted after a prolonged period of normal oceanic subduction, changes in the temperature distribution and stress field of the subducting lithosphere can lead to failure within the lithosphere, and result in detachment of the deeper portion of subducted lithosphere (slab detachment or slab breakoff). We use a 2D time‐dependent numerical model to identify the parameters controlling slab detachment and to estimate breakoff depths and time lengths. Temperature and rheology of subducting continental lithosphere are found to control slab detachment.
