Abstract
Quaternary studies in Poland require an improved integration of lithostratigraphy, biostratigraphy, chronostratigraphy, geochronology, magnetostratigraphy, climatostratigraphy and isotope stratigraphy. The former Polish loess stratigraphic schemes are of historical significance and should be verified using new research methods and implementation of the international unified loess labelling system. Arbitrary stratigraphic correlations should be avoided and a reliable stratigraphic subdivision of the Quaternary of Poland should be based on recognized international standards as well as stratotype sections and areas. This is essential both for the Quaternary sciences themselves and for the needs of the society.

The question of drainage of the Warsaw ice-dammed lake, Central Poland

Abstract
The question of the outflow from the Warsaw ice-dammed lake in Central Poland through the Warsaw-Berlin ice-marginal spillway during the Vistulian (Weichselian) Glaciation is discussed. Many years’ research and published concepts expressed in numerous publications since the beginning of the 20th century are presented. A runoff in the Warsaw-Berlin ice-marginal spillway was treated as impossible during the LGM, because ofa high watershed zone close to Łęczyca. The floor of this ice-marginal spillway is filled by silt and sand series correlated with the Late Vistulian and sand with peat of the Late Vistulian and Holocene. However, a relation of the glaciolacustrine sediments and the spillway floor indicates that the latter is masked by deposits that postdate the outflow episode. Proglacial and extraglacial waters were collected in the Warsaw ice-dammedlake and were drained westwards through the Warsaw-Berlin ice-marginal spillway.
