Innuitian orogeny

Innuitian orogeny (sage green) surrounded by the Slave and Rae cratons (fuchsia) that constitute the northern core of the North American craton (Laurentia).

The Innuitian orogeny, sometimes called the Ellesmere orogeny, was a major tectonic (mountain building) episode 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]
