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
Weathering and clay mineral formation in two Holocene soils and in buried paleosols in Tadjikistan : towards a Quaternary paleoclimatic record in Central Asia
Special issue. Reconstruction and climatic implications of paleosols
The upper part of the Karamaydan section, Tadjikistan, shows the most detailed loess-paleosol sequence yet known for the Brunhes chron, and the central and lower parts of the Chashmanigar section provide similar detail for most of the Matuyama chron
. The aim of this paper is to give a quantitative paleoclimatic interpretation based on the type and amount of pedogenic clay material formation of the paleosols in comparison with 2 holocene soils and thus improve the knowledge of the history of Quaternary
A micromorphological comparison of the loess-paleosol sequence of the Karamaydan section, Central Asia, with the upper part of the Luochuan section, China, clearly indicates that for the Brunhes chron the sequence at Karamaydan is more detailed than
the corresponding section at Luochuan. It provides more paleoclimatic detail, with cold dry stages represented by loess and warm humid stages (interglacials) by paleosols, than even the deep-sea cores.
The S5 is the most prominent paleosol unit in the Chinese Loess Plateau, and is distinguished by its great thickness, dark color, and well-developed clay coatings. Previous studies led to the proposal that the S5 developed under much warmer
and wetter conditions than at present, implying a climatic optimum. However, the S5 is a paleosol complex corresponding in time to a period of weak glacial-interglacial oscillations, as recorded by marine oxygen-isotope stages 15 through 13. To understand
the character of this climatic interval, 2 profiles of the paleosol S5 in the Guanzhong basin were studied (grain-size, mineralogical and chemical data).

In this paper, the A. suggests a correlation of later Pleistocene interglacial paleosols from Normandy (St. Pierre les Elbeuf) in western Europe to the Ukraine in eastern Europe based on soil characteristics and dates from selected key sites.
Les thèmes suivants sont abordés dans l'article : 1. la connaissance du relief permet de dater et de classer les paléosols dans le loess, 2. estimation de la genèse et âge de la pédogenèse, 3. problèmes d'interprétation paléo-écologique, 4
Les changements évolutifs généraux des paléosols des couvertures pédologiques de différents âges, étroitement liés à des changements essentiels du climat et du biote au Pléistocène ayant un caractère irréversible, se traduisent par des changements
Recherches stratigraphiques menées depuis 1980 dans la région des grands lacs de l'est du Congo-Zaïre. Des analyses de paléosols montrent que les phases chaudes humides des Tropiques correspondent aux phases chaudes humides des régions tempérées et
