Problems of Holocene climatostratigraphy on the territory of Poland

100%

Starkel L.

tom Vol. 23

17-21

The presented climatostratigraphy of the Holocene on the territory of Poland is based on a range of biotic, sedimentological, geomorphological and isotopic records, but also takes into account fluctuations of temperature and hydrological regime. The author upholds the traditional division of the Holocene into three thermic phases and discusses in detail distinct fluctuations in the hydrological regime reflected in the alteration of wetter and drier phases. Althrough their profiles tend to be blurred, the lower boundaries are the wetter phases, which set off the transformation of geoecosystems (a process reflected in the first clusters of extreme events), may be used to identify regional stratigraphic subdivisions. The superimposed phases of human activity have much smaller spatial extend.

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.
