The sequence is composed of fluvial-lacustrine and marshland deposits which started to accumulate during the Late Glacial and culminated at the beginning of the Holocene. The highly characteristic changes in the biofacies were linked to changes in the lithofacies within this sequence. A transition in the dominance of moving water species, observable initially in lacustrine species preferring well-lit, well-oxygenated conditions was observed. Eventually, the littoral and eutrophic lacustrine species, as well as marsh-dwellers, became dominant in the profile, marking the emergence of uniform peat land in the Sárrét BasinS pomočjo sedimentoloških in paleontoloških analiz vzorcev iz vrtine Sárrét-Nádasdladány lahko sestavimo popolno okoljsko zgodovino te neotektonske depresije. Zaporedje sestavljajo rečni, jezerski in močvirski depoziti, ki se začnejo v poznem glacialu in se nadaljujejo v začetek holocena. Zelo značilne spremembe v fosilnih zbirih lahko povežemo s spremembami v sedimentaciji. Na začetku prevladujejo vrste, ki živijo v tekoči vodi, te pa kasneje zamenjajo vrste, ki živijo v jezeru, v dobro osvetljenih vodah z dovolj kisika. Kasneje postanejo pogostejše obalne in evtrofične kot tudi močvirske vrste, ki zaznamujejo nastanek šote v kotlini SárrétTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Filozofska fakulteta
