<jats:p xml:lang="en">The Eureka Sound Group, in eastern Arctic Islands, is divided into four new, lithologically distinct formations of regional extent. The oldest is the Expedition Formation of middle or late Campanian to early Paleocene age, consisting predominantly of sandstone and minor shale, that originated as wave dominated delta, barrier island and estuarine deposits; a major shale unit, the Strand Bay Formation of early to middle Paleocene age, that represents basin-wide marine transgresssion (early Paleocene), followed by regressive prodelta and shelf deposits; the Iceberg Bay Formation of middle or late Paleocene to middle Eocene age, consisting of fluvial sandstone and coal (mostly delta plain); and the stratigraphically highest unit, the Buchanan Lake Formation of middle Eocene age, possibly extending into the late Eocene, that consists of syntectonic conglomerate shed from adjacent thrust sheets, and signifying a major phase of the Eurekan Orogeny. Correlations are made with Eureka Sound strata on Bylot Island, Amund Ringnes Island, Lougheed Island, Banks Island and at Lake Hazen.</jats:p>
