Building on previous work, the AA. analyzed high-resolution changes in the low-field magnetic susceptibility, pedology, lithology, and pollen content of these late Pleistocene deposits to compare the Vyazivok stratigraphy with better known loess

L'ouvrage ne porte que sur l'URSS et s'articule en deux grandes parties. La première est un recensement des données paléogéographiques sur le Pléistocène, région par région. La seconde est une tentative de synthèse qui s'efforce de reconstituer le
milieu naturel au Pléistocène avec toutes ses composantes et son évolution. - (FC)

In the study the most typical Pleistocene periglacial processes, forms and deposits are presented. The final conclusion is that the relief of Hungary was heavily reshaped under periglacial climate and the landforms still preserve much
of their periglacial character. The trend of relief evolution was towards planation in the Pleistocene. (DLO).
Ratios of D-alloisolencine to L-isolencine have been determined on freshwater molluscs from 13 interglacial sites in South East England and on marine molluscs and foraminifera from 10 Pleistocene and Upper Pliocene Crag sites in East Anglia. We can
distinguish the Ipswichian, then either one or two interglacials that may be younger than the classical Hoxnian, then the Pleistocene Crags, then the Pliocene Coralline Crag.
Evidence for climatically-controlled carbonatization of soils from Holocene and Pleistocene parent materials have been found by dating soil carbonates. Two phases of soil carbonate formation were recognized; one before peak glaciation (18. 000 years
B.P.) and a second at late Pleistocene-early Holocene time. These two periods reflect rather a humid phase, separated by an arid phase during peak glaciation.
As recently as 7 years ago Quaternary geologists believed that there were no Pleistocene paleosols represented by non-peaty soil horizons (A, B, etc.) in Norway. However, several buried soils of this type have recently been reported and studied
by stratigraphic, magnetic and chemical methods. The presence of these buried Pleistocene paleosols in the interior of Norway (central part of the Fennoscandian glaciations) indicates that glacial erosion was locally less during several glacial cycles than
Stratified sediments, interpreted to be part of the Courtmacsherry Formation Pleistocene raised beach that overlies a marine rock platform near Fethard, south Wexford, were sampled and dated using the technique of Infra Red Stimulated Luminescence
. These are the first age determinations for the Courtmacsherry Formation itself and, as such, represent an important advance in the development of a chronostratigraphy of the Pleistocene in Ireland.
This paper discusses the morphological and geological evidence for Pleistocene neotectonic faulting and uplift in the northeastern part of the Sowie Mountains where the Sudetic Marginal Fault has its maximum deplacement and uplift rates. Although
the greatest uplift was during the Neogene tectonic phases, Pleistocene fault activity was significant and influenced the development of river valleys and foreland alluvial fans. This contradicts with former views.

This paper reports the discovery of an exceptionally thick ash deposit of Middle Pleistocene age in western Epirus, Greece. This ash layer has not been reworked and has a chemical composition that links it to an Italian volcanic source 750 km
distant. The deposit must have been produced by one of the largest Mediterranean eruptions of the past 400,000 yr and should form a distinctive marker horizon in Pleistocene deposits of southern Italy, mainland Greece, and the Aegean Sea.
The AA. focus on the late Pleistocene glacial history of 2 principal massifs (Kisogle Mountain and the massif northwest of Goodnews Lake) in the southwestern Ahklun Mountains. They present detailed glacial-geologic mapping of an area influenced
by both alpine and ice-cap glaciation during the multiple advances of the Pleistocene.

Complex investigations of the glacial deposits of Pleistocene which are of great importance to the national economy are described in the book. The distinguishing of glaciosedimentation cycles of Pleistocene are grounded theoretically, division
and correlation criteria of glacial deposits of different age are presented. A lithogenetic, lithostratigraphic and paleogeographic importance of the composition of glacial deposits of Pleistocene is revealed. The sources of fragmental product and the directions
of the movement of glaciers of different age of Pleistocene are determined and also the questions of the ground moraine formation are solved. Scientific conclusions, experience and methods described in the book are of great importance to the investigations
of glacial deposits widespread in the regions of the Pleistocene continental glaciation.
