The Eurekan Orogeny relates to the tectonic impact of Greenland as an independent lithospheric plate indenting the High Arctic during the Paleocene-Eocene. While the emphasis to date has been on the High Arctic land geology, we highlight marine geophysical evidence for distal tectonic effects to the north: 1) 400 km north of Ellesmere Island, where the elevated southern end of the Lomonosov Ridge reveals flanking local sediment accumulations (35 km wide) at two Paleocene/Eocene stratigraphic levels which suggest discrete episodes of plateau uplift and erosion; 2) north of Greenland, where the Morris Jesup Rise (300 km long, 180 km wide) is formed by a stack of deformed sediments and volcanics; 3) north of Svalbard, where a north-trending continental basement block (>200 km long, 80 km wide) of the Yermak Plateau was affected by northeast directed thrusting. The indenting Greenland plate caused tectonic deformation distributed over a +300 km wide zone east and northeast of Greenland. In the Queen Elizabeth islands, west-directed extrusion of elongated crustal blocks was conditioned by crustal-scale N-S folds represented by formation of the Princess Margareth and Cornwall arches.
