Glacial geology and deglaciation chronology of the area between inner Nordfjord and Jostedalsbreen Strynefjellet, western Norway NORALF RYE, ATLE NESJE, RUNE LIEN, LARS HARALD BLIKRA, OLIANNE EIKENÆS, PER AUDUN HOLE & INGRID TORSNES Rye, N., Nesje, A., Lien, R., Blikra, L. H., Eikenæs, 0., Hole, P. A. & Torsnes, 1.: Glacial geology and deglaciation chronology of the area between inner Nordfjord and Jostedalsbreen - Strynefjellet, western Norway. Norsk Geologisk Tidsskrift, Vol. 77, pp. 51-63. Oslo 1997. ISSN 0029-196X. A lower limit of blockfields is inferred to indicate the maximum heights and thus thickness of the Late Weichselian iee sheet in the inner Nordfjord region. lee movements in this area have been topographically controlled during the entire Weichselian glaciation. Prominent lateral moraines de1imit the Younger Dryas valley glaciers in inner Nordfjord. Subsequent to the Younger Dryas Chronozone, the glaciers retreated rapidly due to calving in the fjord and climatic amelioration. In a later phase of deglaciation, in all probability around the early and middle part of the Preboreal Chronozone, an iee eentre east of Strynefjellet dominated, while the Jostedalsbreen area is thought to have played a minor role as a eentre of iee dispersal. The final deg1aciation was dominated by vertically down-wasting iee remnants in the lake basins and tributary valleys. Terminal moraines in front of several outlet glaciers of Jostedalsbreen beyond the 'Little lee Age' moraines indicate a climatic deterioration at the end of the Preboreal Chronozone. N.
