Engineering-geological problems of loess in Poland

Grabowska-Olszewska, B., 1988. Engineering-geological problems of loess in Poland. Eng. Geol., 25: 177–199.

In Poland, loess covers are limited to a latitudinal belt in the southern part of the country. The covers vary from 2 to 30 m in thickness and the loesses are developed in three major facies: eolian, deluvial and alluvial. Stratigraphically, they represent four major horizons correlated with the Vistulian (Würm) Glaciation and some older ones. The paper presents characteristics of granulometric, mineral and chemical compositions with reference to origin, facies and stratigraphic position of these soils, as well as their lithofacies classification. The classification gives the basis for analysis of local and regional variability in engineering-geological properties of the loess.
