A reliable stratigraphic subdivision of the Quaternary is extremely important, dependent firstly on primary significance of its deposits in geological investigations and every-day life of human societies. In the Cenozoic, the Quaternary is a period of the same stratigraphic rank as the Palaeogene and the Neogene, but it is much shorter. Traditional stratigraphic schemes of the Quaternary were based mostly on other criteria than of the older periods, because studies of the Quaternary were focused mainly on more easily accessible terrestrial deposits and a decisive role in their formation was played by climate-induced processes. These factors forced a specific approach to define the stratigraphic units and to create the stratigraphic subdivisions of the Quaternary. In the Quaternary investigations in Poland, several categories of stratigraphic classification are used, particularly lithostratigraphy (with pedostratigraphy and cryostratigraphy), morphostratigraphy, biostratigraphy (including palynostratigraphy, malacostratigraphy, teriostratigraphy and anthropostratigraphy), magnetostratigraphy, chronostratigraphy (synchronized with geochronology) and climatostratigraphy (combined with oxygen isotope stratigraphy). The main climatostratigraphic units can be treated as corresponding to the chronostratigraphic ones and it enables correlation in a regional and global scale. Acritical overview of the applied stratigraphic categories and the updated stratigraphic subdivision are presented for Poland.

Na mapie zestawiono 261 wybranych stanowisk interglacjału eemskiego na tle głównych stref marginalnych lądolodów skandynawskich w Polsce. Obecność stanowisk osadów jeziornych z interglacjału eemskiego w strefie wysoczyzn polodowcowych położonych między zasięgami lądolodów warty i odry, przy braku na tym obszarze starszych, to jest z interglacjału lubawskiego, osadów w stanowiskach eemskich, jest kolejnym argumentem przemawiającym za uznaniem obu nasunięć lądolodów (odry i warty) jako stadiałów obrębie jednego zlodowacenia. Zlodowacenie to zajmowałoby pozycję chronostratygraficzną zlodowacenia warty (Lindner, 2005), korelowaną z 6 stadium izotopowym tlenu, czyli około 210-130 ka.

The map presents 261 selected sites of the Eemian Interglacial against the background of marginal zones of the Scandinavian Glaciations in Poland (Fig. 1). The appearance of lacustrine deposit sites from the Eemian Interglacial in morainic uplands between the Wartanian and Odranian ice-sheets along with the absence of older interglacial sediments (prior to the Wartanian Glaciation i.e. of the Lublin Interglacial age) at the Eemian sites - is another argument for accepting both the Wartanian and Odranian advances as stadials within a single glaciation. The glaciation would embrace a chronostratigraphic position of the Wartanian Glaciation (Lindner, 2005) as correlated with the 6th oxygen isotope stage i.e. ca 210-130 ka.
