Climatostratigraphic subdivision of the Pleistocene Middle Polish Complex in Poland

The term Middle Polish Complex was introduced by the authors in 2007 as an informal superstage of the younger Middle Pleistocene in Poland. It replaced a previous inconsistent term of Middle Polish Glaciations, composed both of glaciations and interglacials. The Middle Polish Complex comprises deposits of 3 glaciations (Liwiecian, Krznanian and Odranian) and 3 interglacials (Mazovian, Zbójnian and Lublinian). Glacial and lake-marshy deposits of the complex correspond with loess sequences and separating palaeosols. Their common superposition in Poland and recorded palaeomagnetic episodes Emperor, Chegan, Jamaica and Blake of the Brunhes epoch verify a chronology of climatic changes and climatostratigraphic subdivision of the complex. Mutual relation of climate changes and their reference to glacial-interglacial and loessy-palaeosol cycles in neighbouring countries support usefulness to more specified correlations. Successive interglacials and glaciations of the Middle Polish Complex correspond to rhythmic global climate changes reflected by oxygen isotope stages in deep-sea boreholes (MIS11-6
