Abstract

Podział młodszego czwartorzędu Polski przeprowadzono na podstawie krzywej izotopu tlenu dla Atlantyku (M 13519) dla 750 000 lat. Wyróżnione jednostki stratygraficzne udokumentowano datowaniami metodą termoluminescencji (TL) osadów glacjalnych i interglacjalnych. Ciągły zapis zmian klimatycznych w rdzeniach oceanicznych jest podstawą wyróżnienia jednostek stratygraficznych czwartorzędu. STRATIGRAPHIC UNITS OF QUATERNARY IN POLAND Different concentration of oxygene isotopes and different content of diatoms in the ocean depositsreflect climatic fluctuations and allow to estimate their age. The continuous record of the sea surfacetemperature and diatoms content in the Atlantic Ocean is related to the similar climatic changes on thecontinent as it has been recorded in the pollen diagram from the Grande Pile peat bog in France (Fig. 1). This fact proves that ocean cores from the moderate latitudes reflect continental climate as well.In Poland the stratigraphic subdivision of younger Quaternary is based on the oxygen isotopecurve of the Atlantic Ocean (M 13519) concerning 750 000 years. Presented stratigraphic units havebeen documented by TL datings of glacial and interglacial deposits. The continuous record of climaticfluctuations yielded by ocean cores is of fundamental importance for Quaternary subdivision into stratigraphic units.
