加拿大北部“破碎山河”的成因与大陆漂移

Study on the Relationship between the Origin of Broken Plates in Northern Canada and Continental Drift

摘要: 加拿大北部的“破碎山河”是地球上独一无二的，它们是如何形成的？目前关于其成因的模式一直是沿用传统的海底扩张和板块构造的模式解释的，但这种模式在其他地区存在自相矛盾的地方。本文结合作者提出的大陆漂移的源动力——板块自驱动模式，给出了一个北美洲受力模型，说明了加拿大北部破碎山河的成因。该成因模型为我们重新认识北美洲地理环境成因提供了一个新的思路。

Abstract: Broken plates in northern Canada are unique on Earth, how they are formed? The current explana-tion about it is that it was formed by seafloor spreading and plate tectonics model, but this model cannot be explained in many cases and even has contradictory. Combined with the model “source power for continental drifting-plate self-driven mode” by the author, a new genetic model was given in this paper, that is the North America-force model which explains the causes of broken plates in northern Canada. The genetic model pro-vides us a new way to rethink the origin model of the North America geographical environment.
