One of the most interesting findings of the study is that the separation of this proto-microcontinent coincides with a change in the orientation of tectonic spreading, which occurred between 58 and 49 million years ago.
This change was driven by the reorientation of the rift margins of Canada and Greenland, indicating that the structure of the lithosphere had a fundamental control over plate movements.
This research not only provides a detailed explanation of the tectonics in the region but also proposes a model that could be applied to other regions of the world where microcontinents have been identified or could be identified. With a better understanding of these processes, scientists are one step closer to deciphering the tectonic dynamics that have shaped the continents as we know them today.
