Abstract In a large gravel pit 6 km south of the town Sandnes, south of Stavanger, in Norway, the following section is exposed: At the top, 75–70 m above sea-level, an 0.5–3.0 m thick till with large blocks and boulders (A). Below this a bluish-grey marine clay with fossil foraminifera, up to 10 m thick (B). Below this a unit with disturbed layers, among them a cobble silt representing another till; combined thickness of this unit 1–3 m (C). Then follows 2 m of horizontally stratified gravel (D) and 4 m of stratified sand (E). Thereunder lies a 1.5–2.5 m thick layer of very coarse and poorly sorted gravel (F), which rests upon 3 m of well sorted sand and fine sand (G). Below this sand is a disturbed formation of coarse gravel and sand (H); 5 m of this was exposed to the bottom of the excavation, its thickness being unknown. Unit A is correlated with the Main Weichselian stadial (approx. 18–20 000 B.P.), unit B with the Sandnes Interstadial (from more than 20 000 to less than 50 000 B.P.), while unit C is called the Foss-Eigeland Stadial (approx. 50 000 B.P.), which separated the Sandnes Interstadial from the Brorup Interstadial (unit E). Unit G which lies between two glacigenic layers may be correlative with the Rodebæk Interstadial. The section of Foss-Eigeland thus contains an almost complete Weichselian record.
