This project aims to investigate the dynamics of Earth’s tectonics and its plate motions, with the aim of understanding the mechanisms that force single plates or whole-Earth motions’ changes. The Earth’s tectonics follow regular cycles, in every ~500 million years, of continental aggregation and dispersal, which are intervened by periodic destabilisation and rapid reorganisations. What causes the reorganisations and reversal of the tectonics remain standing questions in planetary dynamics. The expected outcomes of the project will provide an understanding of the recent supercontinent formation and its fragmentation into the present-day continents.

该项目旨在研究地球构造及其板块运动的动力学，目的是了解迫使单个板块或整个地球运动发生变化的机制。地球的构造遵循大陆聚集和扩散的规则周期，每隔约5亿年，这一周期受到周期性的不稳定和快速重组的影响。是什么导致了构造的重组和逆转，这仍然是行星动力学中的悬而未决的问题。该项目的预期成果将使人们了解最近的超级大陆的形成及其分裂成今天的大陆。
