Quaternary geology of Jæren and adjacent areas, southwestern Norway

Forkortet. Jæren in southwestern Norway is covered with a sheet of Late Weichselian glacial deposits which in places overlies rather thick units of older glacial and marine deposit. Younger Late Weichselian and Holocene marine sediments, eolian sand and peat cover parts of the Late Weichselian sheet. The distribu- tion of the surficial deposits was mapped, and numerous analyses of grain size, fabric, clastic roundness and pebble counts were used to characterize the depositional environments. On the basis of lithostratigraphical, bio- stratigraphical and cronostratigraphical studies, including datings by differ- ent methods, a stratigraphical model is presented for the Late Weichselian and older deposits. The model is preliminary, since the dating and correlation of deposits older than 25 000-30 000 years B.P. remain uncertain. All units in the model are mentioned in stratigraphical order.
