Glacial geology of the area between Jostedalsbreen and Jotunheimen, South Norway.

Abstract

Ice movement and the course of deglaciation are reconstructed. The age of and the climate during the deglaciation are discussed in the light of equilibrium line displacement, shoreline positions, pollen analysis and radiokarbon datings. The oldest regional ice movement was towards and out of Lusterfjord. Deglaciation is divided into five climatostratigraphic units: the Luster Interstadial (10200 +- 200 to 9800+-200 B.P.), a period of extensive glacial recession; the Gaupne Stadial (9800+-200 to 9500+-200 B.P.), a period of glacial advance and stagnation; a relatively short period of retreat follows this before the glaciers stagnate in the Høgemo Stadial; and finally (after 9100+-200 B.P.), a period of rapidly receding valley glaciers and downwasting of mountain glaciers.
