The Innuitian orogeny, sometimes called the Ellesmere orogeny, was a major tectonic orogeny (mountain building episode) of the late Devonian to early Carboniferous, responsible for the formation of a series of mountain ranges in the Canadian Arctic and Northernmost Greenland. [1] The episode started with the earliest Paleozoic rifting, extending from Ellesmere Island to Melville Island. [2] However, the cause of the orogen remains poorly understood. [3]
