ABSTRACTA turf-banked gelifluction lobe in south-central Norway is described together with detailed14C dating of buried soil material, measurements of current activity, and sedimento-logical, geotechnical and micromorphological analyses. Three stratigraphic units are recognised; a silty sand upper unit (Unit 1) overlying heterogeneous sandy sediments containing organic bands up to 2 cm thick (Unit 2), which in turn overlies a buried soil of thickness 75 cm (Unit 3, the Main Buried Soil) developed on the underlying till. Analyses indicate that the gelifluction and frost creep responsible for the formation of this lobe affected not only till but also colluvial (slope wash) deposits. Particularly in Unit 2, well-sorted layers of fine sand and coarse silt alternating with organic bands, indicate episodic accumulation of colhivium separated by intervals of pedogenesis.Nineteen14C dates were obtained from eight points along the length of the Main Buried Soil and from a vertical section through the lobe, including organic bands. A complex interpretation is outlined, taking into account such factors as Apparent Mean Residence Time, age-depth relationships, and the possible effects of erosion, contamination and natural variability. Environmental reconstruction indicates the following sequence of events. After about 300014C years B.P., an initial colluvial phase covered the Main Buried Soil, interrupted by at least two pedogenic intervals, which began by about 1730 and14C years B.P., Gelifluction is inferred to have been initiated after about 100014C years B.P., the lobe front possibly advancing at an average rate of about 8.4 mm y-1. The Main Buried Soil is considered to have formed during the period between regional deglaciation, approximately 900014C years B.P., and the initiation of colluviation. Palaeoclimatic implications are discussed.
