Sedimentology of Colour Lake, a nonglacial High Arctic lake, Axel Heiberg Island, NWT, Canada
Under modern conditions, the annual contribution of lake shore gelifluction to lake sedimentation is estimated at approximately 15 to 30%. The remainder of the modern annual sedimentation rate of 0.2 mm yr-1 is made up mostly by stream inflow, which also contains geliflucted sediments. Late Holocene...

Under modern conditions, the annual contribution of lake shore gelifluction to lake sedimentation is estimated at approximately 15 to 30%. The remainder of the modern annual sedimentation rate of 0.2 mm yr-1 is made up mostly by stream inflow, which also contains geliflucted sediments. Late Holocene environmental change was also traced through study of sediments from sediment cores. Throughout this period, the contribution of sediment from inflows was significantly higher than today and the lake drainage area was more than double its present size, which increased the sedimentation rate over the last millennia to 0.7 mm yr-1. -from Author |
