Brève description des sables de couverture récents et anciens du S Jutland. La séquence lithostratigraphique dans les sables de couverture est analysée et des datations sont faites par analyse pollinique pour certains des dépôts. La séquence danoise
est tout à fait comparable à la séquence néerlandaise.

To interpret climatic signatures from magnetic susceptibility (MS) in the Barton County loess-soil sequence, the AA. test the influence of particle size and carbonate concentration on magnetic susceptibility. Discussion of the results.
Palynology of Central European loess-soil sequences in Lithology and stratigraphy of loess and paleosols.
Results of paleofloral studies of late Pleistocene sequences at four central European localities: Stillfried (Lower Austria), Dolni Vestonice (Southern Moravia), Paks and Mende (Hungary). Environmental conditions under which loess accumulated
A paleomagnetic record for the Grande Pile lacustrine sequence deposited during the last interglacial-glacial cycle has been constructed based on continuous sampling of a 15-m-long oriented core (GPXX). The present work is intended to assess
the paleomagnetic reliability of the GP sequence by adding magnetomineralogic analysis and subsequent determination of the magnetic fabric properties.
Eemian and Holocene sedimentary sequences on the Belgian coast and their meaning for sea level reconstruction in The Quaternary and Tertiary geology of the Southern Bight, North Sea.
Belgique ; Géographie de l'Europe ; Littoral ; Niveau marin ; Paléo-environnement ; Quaternaire ; Stratigraphie
The Quaternary deposits of the easter part of the present-day Belgian coastal plain comprise two major marine sequences : Holocene and Eemian sedimentary layers. These sequences are composed of coastal, nearshore, perimarine and tidal flat deposits
. In this paper emphasis is put on the comparison of these marine sequences.
The aim of this study was to examine pedogenic formations consisting of massive and paleosolic caliches (calcrete) in the Misis area, and to correlate these units with the underlying strata of the lithological sequence of the Tertiary Adana Basin.
L'identification des niveaux d'occupation, l'étude de la formation du site et de ses remaniements ultérieurs exigent une étroite collaboration entre le géomorphologue et l'archéologue. Exemples fournis par la séquence archéologique de la Sodmein
Etude stratigraphique des sédiments tardiglaciaires de la Mer de Champlain. Mise en évidence de 2 séquences d'écozones à foraminifères. Les résultats obtenus concernant les paléosalinités ne permettent pas de détecter le détournement de l'exutoire

This paper describes the basic stratigraphic sequence and features of paleosols, loess layers, tephra layers, and flood-cut unconformities in the late Quaternary part of the loess record in the south-eastern area of the Channeled Scabland
Stratigraphie, Klima- und Umweltenwicklung der letzren 400.000 Jahre im Saalegebiet und Harzvorland (Forschungsstand 2006)
Stratigraphie, changement climatique et évolution de l'environnement, au cours des 400 000 dernières années, dans le bassin de la Saale et le pré-Harz (état de la recherche 2006)
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
. 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

This review aims to consider the role of micromorphology as a record of paleoenvironmental change, concentrating in particular on recent developments applying a pedosedimentary approach to loess-paleosol sequences, and illustrated by cases studies
Possibility for subdividing apparently homogeneous depositional sequences by combined use of sedimentological, paleontological and mathematical methods
by their grain size parameters and their carbonate content. Parallel to these genetic units the sequence was subdivided from a faunistic point of view, too. The results correlate well with those of the numeric approach.

Les bassins drainant la chaîne de Craigieburn, en Nouvelle-Zélande, ont favorisé la préservation d'une séquence de moraines du Quaternaire tardif. Les âges des moraines ont été déterminés par une datation fondée sur l'examen de la pellicule

Après une présentation des heads et plages suspendues des îles Anglo-Normandes, les dépôts du littoral normand et du Sud de l'Angleterre sont passés en revue. Ce qui permet de proposer une synthèse au niveau de la Manche centrale sur les séquences
côtières, sur les paléoenvironnements et sur les niveaux marins, dans le cadre des stratigraphies régionales.
The sequence of glacial deposits near McCall, Idaho, previously assigned to the Pinedale and Bull Lake glaciations, contains deposits of four different ages. These ages are defined by multiple relative-age criteria, including weathering rinds, soil
development, surface-rock weathering, morainal morphology, and loess stratigraphy.
The application of oxygen isotopic stratigraphy appears to be a useful technique in the chronostratigraphy of subaerial loess sequences, but further data and comparisons are needed particularly in the case of older stages and loess cycles.
, permitted correlation with events both within China and farther afield, and placed the sequence in the global framework of late Cenozoic climatic change. The cave deposits can be divided into 17 layers which are correlated with the great loess sequences (L9
