Abstract

Five major stratigraphical units, each consisting of a number of lithofacies, were recognized in the Lake Boksehandsken area: 1) The lowest unit, outcropping in the coastal sections below ca. 15 m a.s.l. consists of stratified, silty sand, and is interpreted as having been deposited in a near-shore marine environment. It is discordantly overlain by 2) a massive, overconsolidated silty-clayey diamicton. The diamicton is interpreted as a lodgement till. This till outcrops in the coastal sections at 15-25 m a.sl., and is frequently observed on the inland surface to altitudes of at least 70 m. The till is overlain in the coastal sections and in near-coast ravines by 3) a gravelly-sandy-silty stratified diamicton. The stratified diamicton has beds and lenses carrying subfossil shells in abundance, and the unit is interpreted as a glaciomarine sediment with dropstones. The glaciomarine sequence is overlain in the coastal sections by a unit of stratified sands and gravels, representing the emergence of the depositional basin. A chronology for the event stratigraphy is shortly discussed, and it is concluded that the Boksehandsken sequence is of Late Weichselian age. -from Authors
