ResumoThe research history and geological problems of the stratigraphy of Late Pleistocene rocks in Reykjavík, Iceland are reviewed. New data are presented on the stratigraphy and palaentology of the sedimentary record. The Reykjavík sequence rests unconformably on reversed polarity rocks of Early Pleistocene age and includes tillites as well as marine mudrocks and sandstones, terrestrial diamictites, conglometrates, sandstones and lignites. These rocks are exposed along the coasts of Reykjavík and have also been penetrated by several boreholes. The lithostratigraphy, climatic indicators and available dates indicate that the Weichselian glaciation of the area was preceded by an ice free interval with climate that was comparable to the present one in South Iceland. The so called Fossvogur beds and deposits in Seltjarnarnes indicate three glaciations of the area after the last interglacial.
