Abstract

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

Keywords: palaeogeographical evidence, landform evolution, fluvial deposits, local factors, global changes, Younger Dryas, central Poland
