Middle–Late Holocene paleoclimate and weathering history in the Norra Storfjället mountains, Sweden : deglacial record and soil stratigraphy applied to Neoglaciation in lower latitudes

Auteur(s) et Affiliation(s)



Description :
The retreat record of the Stabre Glacier into the Norra Storfjället mountains, after separation from the massive Tärnaån Glacier at some undetermined time in the Atlantic Chron, is documented by recessional moraines in the foreland. While poorly constrained by radiometric dating, the age of the middle group of moraines averages out to less than 4 000 cal 14C yr BP, with the youngest deposits of Little Ice Age (LIA). The physico-mineral-chemical properties of soils/paleosols in recessional deposits across this sequence provide weathering indices over the mid to Late Holocene in the Swedish sub-Arctic climate. It is likely the middle group of deposits represents stillstand of the retreating glacier offset by climatic deterioration with the onset of Early Neoglacial climate which altered the glacial mass balance, at least until termination of the LIA. Correlation to other alpine areas in the middle and tropical latitudes with similar records is attempted and discussed.
