Summary: In the Eurekau ancl Spitsbergen orogens, the Tertiary tectonic clevelopment is similarly two-phase, inclucling an earlier phase oftranspression followecl by a major phase of compression. The first evcnt, which is Iikely Upper-Paleocene to Early Eocene in age, can be correlatecl with the northeasterly displacement of Greenlancl which took place just after chron 25, It corresponels to a regime of transpression with a significant coupling of thc transcurrent ancl convergent componcnts. The scconcl event, which culminatcd areund mid Eocene, is compatible with the chron 24 to chron 21 anel chron 13 northcrly to northwesterly near-orthogonal convergent motion of Grecnlanel relative to Ellesmerc island. It agrces also with the oblique-slip motion which still prevailecl for the same periocl of time between the Greenlancl- Spitsbergcn paleotransfonn, but with a dominared component of convergence across thc plate-bounclary as a result of strain partitioning.
