In a small graben behind the headland, a 600 m thick succession of Eocene basalt lavas and sediments is exposed. The Igtertivâ Formation comprises a 300 m thick main succession of flows dated to 49.09 ± 0.48 Ma, overlain by sediments of the Bopladsdalen Formation and the Karbbedalen Formation.

Pebbles of alkaline rocks like malignite and tinguaite are found in the sediments, in the conglomerates and in screes in the area.
