A common feature of tectonic reconstructions is the migration of subduction zones and their interactions, resulting in complex tectonic patterns. Reduced migration rates, uplift, strong rotations, and slab break-off are all tectonics features commonly associated with convergent margin interactions, showing that while subduction zones' motions fundamentally shape tectonics settings, their interactions hold the key to their complexities. Fundamental properties such as slab buoyancy, dip direction, and coupled mantle flow determine the motions of single hinge zones. When these zones approach, stress transfers between the slabs through the lithosphere and the mantle, thereby altering the subduction force balance, favoring, opposing, or diverting further motions. We illustrate the range of configurations reported in tectonic reconstructions and address their dynamics through the results of analog and numerical models of subduction dynamics in the upper mantle. The Cenozoic evolution of the Mediterranean provides relevant examples of such interactions, where the coeval activity of several subduction zones during the Africa-Europe convergence has strongly overprinted the current tectonics. A comparison of new analog models with the deep dynamics of the Mediterranean shows how the interactions among slabs and mantle may have shaped the distribution of basins and mountain belts, their uplift, and volcanism in this tectonic province.

构造重建的一个共同特征是俯冲带的迁移及其相互作用，从而形成复杂的构造模式。减小的迁移速度，隆升，强烈的旋转和板块折断都是与收敛边缘相互作用有关的构造特征，这表明俯冲带的运动从根本上决定了构造背景，但它们的相互作用却是其复杂性的关键。基本特性（如平板浮力，倾角方向和耦合的地幔流动）决定了单个铰链区的运动。当这些区域接近时，应力在板之间通过岩石圈和地幔传递，从而改变俯冲力平衡，有利于，抵抗或转移进一步的运动。我们说明了构造重建中报告的构造范围，并通过上地幔俯冲动力学的模拟和数值模型的结果来解决其动力学问题。地中海的新生代演化提供了这种相互作用的相关例子，其中在非洲-欧洲融合期间几个俯冲带的同期活动强烈地覆盖了当前的构造。通过将新的模拟模型与地中海的深层动力学进行比较，可以看出板块和地幔之间的相互作用如何影响了这个构造省份的盆地和山脉地带分布，它们的隆升和火山作用。地中海的新生代演化提供了这种相互作用的相关例子，其中在非洲-欧洲融合期间几个俯冲带的同期活动强烈地覆盖了当前的构造。通过将新的模拟模型与地中海的深层动力学进行比较，可以看出板块和地幔之间的相互作用如何影响了这个构造省份的盆地和山脉地带分布，它们的隆升和火山作用。地中海的新生代演化提供了这种相互作用的相关例子，其中在非洲-欧洲融合期间几个俯冲带的同期活动强烈地覆盖了当前的构造。通过将新的模拟模型与地中海的深层动力学进行比较，可以看出板块和地幔之间的相互作用如何影响了这个构造省份的盆地和山脉地带分布，它们的隆升和火山作用。
