Supercontinents have existed at several times in Earth history; the best known is Pangea, which contained most of the Earth's continental crust from about 350 to about 200 million years ago. Pangea was built from several separate continents, themselves derived from earlier supercontinent breakup. The proposed program of research will investigate the convergence and amalgamation of these continents, which came together in a series of collisions, building the Appalachian mountain range of North America and the Caledonides of NW Europe.

超级大陆在地球历史上存在过好几次；最著名的是盘古大陆，它包含了大约3.5亿到2亿年前地球大陆地壳的大部分。盘古大陆是由几个独立的大陆组成的，而这些大陆本身是由早期的超大陆分裂而来的。拟议的研究计划将调查这些大陆的融合和融合，这些大陆在一系列碰撞中走到一起，形成了北美的阿巴拉契亚山脉和欧洲西北部的喀里多尼德山脉。
