dc.description.abstract | This study focuses on the sedimentary characteristics and the chronostratigraphy of Holocene massflow deposits recognized in a lake-fill sedimentary succession. These deposits in lake Ulvådalsvatnet, western Norway, are discrete, sharp-bounded units of sand-sized sediment, running from gravelly and graded to silt-rich, and characterized by low total carbon and water contents. They are rich in terrestrial macroflora detritus, dark brown in colour, and interpreted as high-density turbidity current deposits attributed to subaerial debris flows that plunged into the lake. Thirty-three 14C AMS dates were derived from three cores, and though the ages are somewhat inconsistent (macroflora invariably younger than bulk sediment samples), they indicate a marked increase in debris-flow processes after c. 2200 cal. yr BP, considered to reflect increased occurrence of heavy rainstorms. | en_US |
