Is this Gondwana Land? Serious question.
Yes, it appears so. I guess the crux of the article is that most of the other remote islands around there had a different age crust - probably much older. This is relatively young crust.
The North American Craton is an old and stable part of the continental lithosphere, which consists of the Earth's two topmost layers, the crust and the uppermost mantle, centered in the present N.America land mass. As such it has been present in the last several Super-Continents of Gondwana, Euramerica, Pangaea and Laurasia.
Someone Gondwana answer that question? /r
