Eastern Canada has a rich geologic history, spanning ~4 billion years of tectonic evolution, and likely encompassing the beginning of the plate-tectonic processes of the Earth. Models of present-day crust and upper-mantle structure, in conjunction with studies of surface geology, are key to understanding the forces that shape the continents and the nature of the interactions between the plates and the convecting mantle beneath.

加拿大东部拥有丰富的地质历史，跨越约40亿年的构造演化，并可能包括地球板块构造过程的开始。现今地壳和上地幔结构的模型，结合表面地质学的研究，是理解塑造大陆的力量以及板块和下面对流地幔之间相互作用的性质的关键。
