Kap Kobenhavn Member B Unit B1 (Pleistocene of Greenland)

Where: Greenland (82.4° N, 21.0° W)

• Paleocoordinates: 82.1° N, 16.7° W (Wright 2013)

• coordinate estimated from map

• local area-level geographic resolution

When: B Member (Kap Kobenhavn Formation), Early/Lower Pleistocene (2.6 - 0.8 Ma)

• up to 35 m thick, lowermost unit in member "B"

• member-level stratigraphic resolution

Environment/lithology: shoreface; sandy siliciclastic sediments

• Bennike (1990) interpreted the unit as representing back and foreshore and shoreface environment.The sediments were deposited during a transgression where sedimentation and sea level kept pace.
• Dominated by parallel-laminated sandy sediments up to 35m thick. The upper contact to unit B2 is gradational. Mollusc shells are sparsely present and at least the upper part of the unit is marine.
