Hyperborean Platform
Hyperborean Platform
a hypothetical Precambrian continental platform that was located in the area of the present-day Arctic Ocean north of the Novosibirskie Islands, Wrangel Island, Alaska, and the Canadian arctic archipelago and east of the underwater Lomonosov Ridge. After the late Mesozoic period most of the hyperborean platform was deeply submerged and covered by the ocean, and it lost its continental character (the Beaufort and Makarov basins). According to geophysical (aeromagnetic) data, the Mendeleev Ridge and adjacent regions of the arctic shelf may be relicts of the hyperborean platform.
