Glacial and periglacial processes, their landforms, influences of cryogenic destruction, and repeated freezing and thawing effects in rocks and their weathered mantle are described. Main features and dynamics of present-day and former glacial
and periglacial environments are presented as an evidence of significant global change of various landscapes in the Quaternary epoch. Knowledge of glacial and periglacial processes and landforms provides a background for understanding the present-day global change
The AA. use cosmogenic nuclide techniques to test the hypothesis that the tors of the Parkajoki area and, by inference, the surrounding landscape, are in fact relict features that have persisted through one or more glacialcycles. If the tors

A variety of factors include climatically induced changes of the river runoff and sediment load, glacial advances and rapid variations of the base level, as well as the influence of the tectonic factor. The first-order climatic cycles are reflected
to lie between 47 and 68 m per glacial/interglacial cycle of 100 ka. This, combined with an estimated duration of glaciation, implies glacial erosion rates in agreement with modern process measurements.
The Antarctic ice sheet during the last glacial interglacial cycle : a three-dimensional experiment
Un modèle thermo-mécanique complètement tri-dimensionnel pour la couche de glace de l'Antarctique entier est employé pour simuler la réaction de la couche de glace durant le dernier cycle glaciaire-interglaciaire, en ce qui concerne les conditions
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 glacialcycles than

been glaciated during multiple glacialcycles. The most extensive phases of glaciation appear to have occurred during the Middle Pleistocene.
The evidence for glacial and periglacial activity has been studied for over 120 years and it is possible to identify 3 phases of development in this area of research. First, a pioneer phase, second, a mapping phase, and, third, an advanced phase
characterised by detailed understanding of the geochronology of glacial sequences using radiometric dating alongside detailed sedimentological and stratigraphical analyses. It is now clear from radiometric dating programmes that the Mediterranean region have
The glacial extent and glacial advance/retreat asynchroncity in East Asia during Last Glaciation
New dates for last glacialcycle in Tibetan bordering mountains and in East Asia show the glacial extent during the early/middle (MIS3-4) stage is larger than that of the late stage (MIS2) in last glacialcycle. It is asynchronous with the Northern
The glacial and periglacial geomorphology for the Simen and Bale Mountains in Ethiopia is reviewed. The Simen Mountains are mostly absent of relict perglacial landforms and today host a variety of miniature cryogenic phenomena. The Bale Mountains
Magnetomineralogy and revised excursions for the last interglacial-glacialcycle in the Grande Pile lacustrine sequence, France
A paleomagnetic record for the Grande Pile lacustrine sequence deposited during the last interglacial-glacialcycle has been constructed based on continuous sampling of a 15-m-long oriented core (GPXX). The present work is intended to assess
Reinterpretation of Late Quaternary sediment chronology of Lake Biwa, Japan, from correlation with marine glacial-interglacial cycles
The AA. propose a new age scale for the late Quaternary sediments of Lake Biwa which they have devised by establishing a paleoclimatic linkage between the lacustrine sediment record and the well-dated marine record of glacial-interglacial cycles.
Apports détritiques au milieu glacio-marin| processus et milieux de dépôt| modification des faciès liés aux cycles d'avancées et retraits glaciaires et niveau marin relatif.
The A. describes and interprets patterns of late Midlandian glacial bedforms in the Omagh Basin, north central Ireland, and reconstructs the position of ice centres and margins during ice buildup and decay. He makes inferences on the internal

The AA. present 4 glacial geomorphic maps of Llanquihue drift in the region of the southern Lake District, Seno Reloncaví, and the eastern half of northern Isla Grande de Chiloé, Chile. These maps form the basis of an interdisiplinary research
. But, these sequences can fill the gaps of the glacial stratigraphy existing since the Elster glaciation. With Eem and Holocene it comprises twenty climatically small cycles with interstadials/intervals and stadials. Fauna and the history of fauna and vegetation
At the time being, the glacial stratigraphy prevails in this region. It is based on the glacial series and on events geologically connected with them. It doesn't consider, or only very little, the sequences in the periglacial and their biology
