Eurekan orogeny

The Eurekan orogeny was a Phanerozoic mountain building event that created the Eurekan Fold Belt on Ellesmere Island in Nunavut, Canada.[1][2] Deformation initiated in the Late Cretaceous, during which time the Sverdrup Basin began to fragment and fold in response to the counterclockwise rotation of Greenland, caused by seafloor spreading in the Canadian Arctic Rift System.[1][3] The Eurekan orogeny terminated when seafloor spreading in the Labrador Sea ceased about 33 million years ago during the Oligocene epoch.[4]
