The definition of glaciotectonics to include both the effects of glaciodynamic processes and the effects of glacioisostatic processes has been generally accepted. In Poland, the glaciotectonic style of the Wartian zone is one of the most distinctive features of the Saalian area; glaciotectonic symptoms are numerous in the western part, but disappear in the east. Such a division extends beyond the Polish borders - as continuous thrust ridges in the west and as a sporadic phenomenon in the east. Attention is drawn to the relationships between geological structure and morphological features; they include such cases as : a direct reflection of thrusts in convex land forms, low-relief areas and relief inversion (in relation to the structure). Much importance has been attached to the marginal zone of the Łódź Plateau in Middle Poland. This paper reviews the main genetic hypotheses which, usually, are based on the mechanism, rather than palaeogeographical conditions. Despite much discussion, several problems remain, e.g.: -   why, allowing that the mechanism was similar, are there such regional differences; -   why are the marginal zone of the Warta Stadial and the western part of Europe so well endowed in this respect; -   could palaeoclimatic conditions (different patterns of glaciation and déglaciation), and could postglacial vertical compensatory movements have conditioned the regional variation?
