AbstractA new site with Lateglacial palaeosols covered by 0.8 - 2.4 m thick aeolian sands is presented. The buried soils were subjected to multidisciplinary analyses (pedology, micromorphology, geochronology, dendrology, palynology, macrofossils). The buried soil cover comprises a catena from relatively dry (’Nano’-Podzol, Arenosol) via moist (Histic Gleysol, Gleysol) to wet conditions (Histosol). Dry soils are similar to the so-called Usselo soil, as described from sites in NW Europe and central Poland. The buried soil surface covers ca. 3.4 km2. Pollen analyses date this surface into the late Allerød. Due to a possible contamination by younger carbon, radiocarbon dates are too young. OSL dates indicate that the covering by aeolian sands most probably occurred during the Younger Dryas. Botanical analyses enables the reconstruction of a vegetation pattern typical for the late Allerød. Large wooden remains of pine and birch were recorded.

A study of the stratigraphic sequence (14C and amino acid age control), marine bivalve faunal changes, and palynology of buried soils and organic-rich sediment collected from the Clyde Foreland Formation in the extensive cliff sections of the Clyde foreland, eastern Baffin Island, N.W.T., suggests the following last interglacial – Foxe (last glaciation) glacial – present interglacial sequence.(1) Cape Christian Member (ca. 130 000 years BP?)Consists of the Sledgepointer till overlain by the Cape Christian marine sediments. In situ molluscan fauna, collected from the marine sediments, contain a moderately warm bivalve assemblage. A well-developed soil that formed on the marine sediments (Cape Christian soil) contains an interglacial pollen assemblage dominated by dwarf birch. U-series dates of > 115 000 and ca. 130 000 years BP on molluscs from the Cape Christian marine sediments suggest that they were deposited during the last interglaciation, here termed the Cape Christian Interglaciation. The development of a subarctic pollen assemblage in the Cape Christian soil has not been duplicated during the present interglaciation, suggesting higher summer temperatures and perhaps a duration well in excess of 10 000 years for the last interglaciation.(2) Kuvinilk MemberConsists of fossiliferous marine sediments, locally divided by the Clyde till into upper and lower units. The Clyde till was deposited by the earliest and most extensive advance of the Foxe (last) Glaciation. Kuvinilk marine sediments both under- and overlying the Clyde till contain the pecten Chlamys islandicus, indicating that the outlet glacier advanced into a subarctic marine environment. Amino acid ratios from in situ pelecypod shells abovę and below the Clyde till are not statistically different, but contrast markedly with ratios obtained from the same species in the Cape Christian Member. Organic horizons within the Kuvinilk marine sediments contain a relatively rich pollen assemblage, although 'absolute' counts are low.(3) Kogalu Member (> 35 00014C years BP)Sediments of the Kogalu Member unconformably overlie those of the Kuvinilk Member, but are of a similar character. The dominant sediments are marine in origin, but in places are divided into upper and lower units by the Ayr Lake till. Amino acid ratios from in situ shells above and below the Ayr Lake till are indistinguishable, but substantially less than those in the Kuvinilk Member, suggesting the two members are separated by a considerable time interval. Radiocarbon dates on shells in the Kogalu marine sediments range from 33 000 to 47 700 years BP, but these may be only minimum estimates. The sea transgressed to a maximum level 70–80 m asl, coincident with the glacial maximum. Subarctic marine fauna of interstadial–interglacial character occur within the Kogalu marine sediments.(4) Eglinton Member (10 000 years BP to present)A major unconformity exists between the Kogalu and Eglinton Members. Ravenscraig marine sediments were deposited during an early Holocene marine transgression–regression cycle; the oldest dates on these sediments are ca. 10 000 years BP. Locally a vegetation mat occurs at the base or within the Ravenscraig unit. Pollen from these beds is sparse, but indicates a terrestrial vegetation assemblage as diverse as that of today. There is no evidence that Laurentide Ice reached the foreland during the last 30 000 years. Eolian sands that overlie a soil developed on the marine sediments record a late Holocene climatic deterioration. Pollen in organic-rich sediments at the base of, and within, the eolian sands record a vegetation shift in response to climatic change.

In this work we present the results of spore and pollen analysis of forest soils from the Zvenigorod biological station of Moscow State University (Moscow Region, Russia). A comparative analysis of forest soils formed on the site of historical fields of the XVIII–XIX centuries and beyond showed that a specific complex of pollen and spores remains in the residual arable horizons, characteristic only of soils that have passed through the stages of plowing and fallow. It includes pollen from cultivated cereals and arable weeds (buckwheat, cornflower blue), spores of the mace-shaped plaunus (Lycopodium clavatum), as well as spores of the mosses Riccia glauca and Anthoceros spp. The latter are exclusive indicators of fallows, since they are practically not found in other habitats. The identified pollen indicators can be used in landscape and archaeological research to interpret the data of spore-pollen analysis of cultural layers, buried soils, gully-ravine sediments. They can also be used to define the boundaries of ancient fields under modern vegetation.

In the article is analyzed the soils’ properties in near-highway road strips of M-10 Lviv- Krakovets with width up to 150 m. Within the near-road strips of the highway, have been established 12 experimental polygons under forest, meadow vegetation and agricultural lands. On each polygons from soils profile samples are selected the most common soils: sod-podzolic, formed on fl uvio-glacial and gray-forest soils formed onloess loam. Completed description of soil profiles to depth of 0-100 cm. Part of experimental soils are formed under hornbeam-beech forests (11, 12 polygons) and oak-hornbeam-pine (4, 6, 7, 8 polygons). The researches revealed that in soil profiles at different depths are lie buried in eolian forms of relief (dunes) with different steepness of slopes. The steepness of the walls of the superficial layers of the dunes varies from 10 to 30°. In the research profiles of near-highway soils on the surface of the dunes, fi nd presence of progumed fragments of strips up wide to 2–3 cm. On the territory of the Nadsyanska moraine-zandrova alluvial plain at a distance of 50 m from the roadway (polygon 2, in the valley of the river Shklo, where the grassland vegetation is predominant, the turfy shallow gluten sandy soils are formed on alluvial deposits) discovered two low-power buried humus horizons who inherited a deflationary relief. Their steepness on the surface of the dunes is about 10 °. In polygon 3, the incision is laid in the micro threshold of the ancient relief, where the vegetation is represented by a spruce forest with oak impurities. In the profile of sod-hidden-podzolic sandy soil, on the surface of buried dunes which have steep walls 10-20°, are observed a humus layers . In the polygon 12, which is laid in the southwestern spurs of Roztochya 1,5 km north of the village of Birky in the hornbeam forest, steepness of the walls superficial layers of dunes of western exposition ranges from 10 to 12°. Soil is a clear-gray forest-loamy on loess loamy. In the soil profi les have been identified the following chemical elements: Pb, Zn, Co, Cu, Ni, Mo, Cr, Mn, V, Ba, Sr, Zr, Fe, Ti, Sn. The researches have established that in the territory of the Nadsyanska moraine-zandrovu alluvial plain, and in the southwestern spurs of Roztochchya, widespread buried dune relief. Based on our research, we propose to consider the issue of the allocation of types (subtypes) in soil legends, to investigate the defilations and inter deflation periods of their formation. Key worlds: near-roads strips, soil profile, deflation forms, buried soils, fragments of humus layers.

The Lubbock Lake site, on the Southern High Plains of Texas, contains one of the most complete and best-dated late Quaternary records in North America. A total of 11714C dates arc available from the site, determined by the Smithsonian and SMU Laboratories. Of these dates, 84 have been derived from residues (humin) and humates (humic acids) of organic-rich marsh sediments and A horizons of buried soils. Most of the ages are consistent with dates determined on charcoal and wood, and with the archaeologic and stratigraphic record. The dates on the marsh sediments are approximate points in time. Dates from the top of buried A-horizons are a maximum for burial and in many cases are close to the actual age of burial. Dates from the base of the A-horizons are a minimum for the beginning of soil formation, in some cases as much as several thousand years younger than the initiation of pedogenesis. A few pairs of dates were obtained from humin and humic acid derived from split samples; there are no consistencies in similarities or differences in these age pairs. It also became apparent that dates determined on samples from scraped trench walls or excavations that were left open for several years are younger than dates from samples taken from exactly the same locations when the sampling surfaces were freshly excavated.
