The Role of Past Climatic Variability in Fluvial Terrace Formation, a Case Study from River Mureş (Maros), Romania

Fluvial terrace formation is a complex process governed by the interplay of climatic and tectonic forcings. From perspective, an incision usually related to transitions, while valley aggradation attributed glacial periods. We have reconstructed Late Pleistocene fluvial terraces along middle, mountainous section temperate zone river (Mureş/Maros) in order identify roles different periods potential vertical displacement development. Investigations were based on two profiles representing levels. The subjected sedimentological detailed geochronological analyses using optically stimulated luminescence (OSL). results indicated that investigated represent events coinciding with transition However, joint MIS 3 period can be identified at both them. Thus, relatively mild but highly variable climate facilitated sediment mobilization from upland catchments. On other hand, there no evidence under cold stable 2. setting favours site. Based our results, we concluded timing main was controlled primarily forcing. model recognised might also applied rivers region.
