Glacial-marine sediment comprises most of the sediment in the sandy lutites, pink-white layers, and .
Authigenic ferromanganese particles and Foraminifera frequently occur in significant quantities in the silty lutites but are generally rare in the other sediment types. The dominance of glacial-marine sediment throughout the stratigraphic section of the Eastern Cordillera supports the theory of more or less continual ice-transport of sediment to the Arctic Ocean for a minimum of . 4 .
Stratigraphy and glacial-marine sediments of the Amerasian Basin, Central Arctic Ocean. In total, six physiographically distinct areas are outlined. In five of these, cores can be correlated over large distances through characteristic patterns in sediment physical properties.

The Amerasia Basin, or Amerasian Basin, is one of the two major basins from which the Arctic Ocean can be subdivided (the other one being the Eurasian Basin). The triangular-shaped Amerasia Basin broadly extends from the Canadian Arctic Islands to the East Siberian Sea, and from Alaska to the Lomonosov Ridge. The basin can be further subdivided based on bathymetric features; these include the Canada Basin, the Makarov Basin, the Podvodnikov Basin, the Alpha-Mendeleev Ridge, and the Chukchi Plateau.

Amerasia Basin is the product of two phases of counterclockwise rotational opening about a pole in the lower Mackenzie Valley of NW Canada. The symmetry of the proto-Amerasia Basin was disrupted by clockwise rotation of the Chukchi Microcontinent into the basin from an original position along the Eurasia margin about a pole near 72°N, 165 W about 14. –140 Ma. Phase 2 opening enlarged the proto-Amerasia Basin by intrusion of mid-ocean ridge basalt along its axis between about 131 and 12. Ma.
