On the basis of studies of many stratigraphical profiles, together with radiocarbon dates, Thorium‐Uranium dates and amino‐acid dates, the following preliminary stratigraphy is proposed: (1) Late Weichselian. Stavanger Stadial. The glacier covered the coast and deposited the upper drift sheet. ‐ (2) Middle Weichselian. (a) Sandnes Interstadial (30,000?‐39,000 years B.P.). Thick units of marine deposits underlie the Stavanger Stadial drift. The lithology, the foraminiferal fauna, the molluscan fauna and the pollen flora all record cold, partly near‐ice environment during their deposition. Elements of a boreal type foraminiferal fauna suggest that certain phases of the Sandnes Interstadial could have been slightly warmer. The shore level was very high. (b) Jæren Stadial (40,000† 1000 years B.P.). Tills and glaciomarine deposits at several locailites are correlated with a Jæren Stadial. (c) Nygaard Interstadial (41,000–50,000? years B.P.). Marine deposits representing a low shore‐level phase, record cool to cold conditions. ‐ (3) Early Weichselian. (a) Karmøy Stadial (older than 47,000 years B.P.). Gravelly and very bouldery tills at low stratigraphical levels in several prifles are correlated with a Karmøy Staidial.(b) Older deposits. Marine deposits which lie below the Karmøy Stadial till and on top of Eemian deposits at Bø II on Karmøy are being studies.
