Abstract

The Carbonate Member of the slope-and-basin facies Hazen Formation has five subdivisions on northeastern Ellesmere Island. Four of these can be mapped individually and correlated over at least 100 km. The same units are lithologically indistinguishable from strata of North Greenland. Correlated units include the lower and upper parts of the Aftenstjernesø Formation (subdivisions A and B, respectively) and the Henson Gletscher (subdivision C) and Kap Stanton (subdivision D) formations of adjacent Nyboe Land. Biostratigraphic data from the North Greenland sections indicate that the four lower subdivisions of the Hazen Formation are equivalent in age to the Scoresby Bay, Parrish Glacier, and Cass Fjord formations of the adjacent Franklinian shelf succession. An additional constraint on the local upper age limit of the Hazen Formation is provided by a gradational contact with the Cape Clay Formation along the shelf margin.
