Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood. New computational methodologies to simulate the evolution of the plate-mantle system will be used to study how the upper mantle emerges as a thermo-mechanically distinct boundary layer, how this emergent structure relates to anisotropy in the upper mantle, and how it is affected by cross-scale effects controlling fault zone behaviour and crustal dynamics.

板块构造在地球的演化和动力学中发挥着至关重要的作用，影响着生命的多样性、矿化和地壳动力学。尽管具有重要意义，但物质结构和板块构造如何以及在什么条件下从原行星中出现的情况尚不清楚。模拟板块-地幔系统演化的新计算方法将用于研究上地幔如何作为热机械独特的边界层出现，这种出现的结构如何与上地幔的各向异性相关，以及它如何受到控制断层带行为和地壳动力学的跨尺度效应的影响。
