Definition of subfossil meandering palaeochannels
Authors:Karol Rotnicki  Ryszard K Borwka
Institution:Karol Rotnicki,Ryszard K. Borówka
Abstract:The determination of the bottom of a subfossil meandering palaeochannel is important for investigations of the palaeohydrology of valley bottoms, and crucial for the quantitative estimation of past river discharges. The authors present a procedure on the basis of which the bottom of a palaeochannel can be precisely determined. It is based on an analysis of the stratigraphic variability of such features of deposits as: mean diameter, standard deviation of the grain-size composition, the percentage of sand, and ignition loss.
Keywords:Subfossil meandering palaeochannel  Past river discharge  Palaeodischarge  Determination of subfossil and fossil palaeochannel bottoms
