A. Lysa et Gd. Corner, LATE PLEISTOCENE GLACIAL-DEGLACIAL FACIES SUCCESSIONS AND GEOLOGIC HISTORY AT VUOLGAMASJAKKA, FINNMARKSVIDDA, NORWAY, Norsk geologisk tidsskrift, 74(1), 1994, pp. 9-23
A 50 m high river section at Vuolgamasjakka, Finnmarksvidda, Norway, h
as been studied with regard to lithofacies, glaciotectonics and geolog
ic history. Six formations reveal a history of four glacial events and
two deglacial events spanning the Weichselian back to the Saalian. Ic
e-free conditions are represented by deglacial sediments consisting of
proximal to distal outwash facies and, at one horizon, delta foreset
beds deposited in an ice-dammed lake- These sediments occur together w
ith tills in stacked glacial-deglacial successions. Four kinetostratig
raphic units are recognized on the basis of glaciotectonic structures,
till fabrics and palaeocurrent directions. Glaciotectonic structures
were formed in both frozen and unfrozen sediments during successive gl
acier advances.
