Local evidence of landform evolution vs. global changes - A case of Younger Dryas study in the upper Ner Valley system, central Poland

Abstract

Domination of the fragmentary or full of sedimentation gaps records causes the necessity of asking about criteria for distinguishing between global factors and local changes in the landform evolution. This study has been conducted in the upper Ner Valley system at the Lublinek site, west of d, central Poland. On the example of the Younger Dryas events in fluvial environment it has been shown that palaeogeographical evidence depends on the maturity of the landform and its position in a system. When dealing with a discontinuous record, only reconstructions of the tendency of evolution as well as its effects over a longer time period may describe the specifics of the environment in a given period, while a comparison of different parts of the system may enable the elimination of local factors.
