  • Pedological regional variations in well-drained soils, Denmark
  • Soil profile investigations were carried out within a national 7 km grid. The profiles were classified according to the 1974 FAO-Unesco Soil Classification System. This paper describes the regional variations in soil profile development
  • The establishment of pedological soil data bases in Denmark
  • Banque de données ; Classification des sols ; Danemark ; Géographie physique ; Profil pédologique ; Pédologie
  • La construction d'un pipeline de la mer du Nord à travers le Danemark a permis la description de quelque 835 profils sur les bases de la FAO. Le système de classification appliqué, les analyses, le système de conservation des données et les
  • Pedology and mineralogy of loess profiles at Kapela-Batajnica and Stalać, Serbia
  • Profiles with multiple paleosols developed in loess at Kapela-Batajnica and Stalać were studied by chemical, physical and mineralogical methods to determine paleoclimatic changes through the Pleistocene. The cyclic nature of sedimentary
  • and pedogenetic processes is indicated by the CaCO3 content and silt and clay mineralogy. These 2 profiles provide an opportunity to compare the paleoclimatic history of 2 areas, one (Kapela-Batajnica) with an essentially continental influence similar
  • Talus and pediment flatirons erosional and depositional features on dryland cuesta scarps in Arid and semi-arid environments. Geomorphological and pedological aspects.
  • In comparing similar slope forms of the Colorado Plateau and southern Morocco, the A. studies whether the alternating climatic conditions have had a significant bearing on the processes which, through erosion and deposition, shaped the profile
  • Pedology of soils within the spray zone of the Victoria Falls (Zimbabwe)
  • Six profiles were sampled in the Victoria Falls National Park in order to investigate the influence of the abundant spray of the falls on the pedogenesis in the otherwise semi-arid environment. Chemical, mineralogical and micromorphological analyses
  • Turf-bearing topsoils on the central Tibetan Plateau, China : pedology, botany, geochronology
  • mats around Nagqu, 4 profiles were subjected to pedological, paleobotanical and geochronological analyses concentrating on soil properties, phytogenic composition and dating of the turf. The results show that the turfs result from the transformation
  • Gold mass balance in lateritic profiles from savanna and rain forest zones
  • In this paper, the gold behavior in laterites was compared under a tropical contrasted climate in Banankoro, South Mali, and under an equatorial climate in Yaou, French Guiana. Gold distribution was studied in detail in terms of pedologic horizons
  • , and mass balance calculations of gold were applied to both sites in order to evaluate the extent of gold mobility for each type of weathered profile.
  • Le profil quaternaire de Hagelstadt dans les collines tertiaires bavaroises
  • On the northern margin of the Bavarian Tertiary Molasse-Hills one can find the brickyard of Hagelstadt in the vicinity of Regensburg, with its thick Quaternary profile. The profile's geological and pedological structure is described in detail
  • Pedological analyses and thermoluminescence dating were carried out on two soil profiles in the alluvial plain of the Orituco River, to determine if the chemical properties of the soil subhorizons are related to the paleoclimatology of the region.
  • The pedological development in a sandy loamy soil in Northern Jutland, Denmark, has been described. The profile was strongly leached, a clay migration has taken place, and a marked Bt-horizon was developed. The Bt-horizon was later slightly
  • Some pedological features affecting the permeability of hillside soils in Caydale, Yorkshire
  • Dans deux parcelles expérimentales aux conditions topographiques, lithologiques et pédologiques semblables, couverte l'une par de la pelouse, l'autre par des fougères, on a observé une plus grande perméabilité dans la partie supérieure du profil du
  • of Cd, Cr, Cu, Zn, Pb, and Ni within soil profiles were checked. Relationships among elements and other pedological parameters, such as organic carbon content, pH, texture, etc., were investigated. Lastly, the possible risk of contamination was assessed
  • . Results show that pedological processes similar to those responsible for the development of steppe chernozems are active even at very high elevations. In order to verify the degree of accumulation and possible ecotoxicity, the distribution and mobility
  • Die geomorphologisch-bodengeographische Deutung der pleistozänen Sedimente und der fossilen Boden an der Playa de Baranan (westl. La Coruna) und bei Cangas de Foz (Nord-Galizien). (The geomorphological-pedological interpretation of the Pleistocene
  • Upper Pleistocene sediment-soil profiles were investigated from a rock basement at 3-5 metres u.s.l. and a coastal terrace at 25 metres u.s.l. at two sites in northern Galicia/north-west Spain (Playa de Baranan, west of La Coruna, and Cangas de Foz
  • The pedological regionalization of the Subcarpathian depression Cracaˇu-Bistriţa
  • Using a taxonomy based of the pedological and geographical reality, this paper is a synthesis of the previous research of the A., seeing the soil both as a productive and a geographical component of the landscape. - (E. Rusu).
  • This study attempts to apply pedology to resolve the factors controlling the geomorphic evolution of terraces in the Pakua tableland. In this study, the weighted mean profile development index (PDI or WPDI) and the amounts of Fe and Al in soils
  • The mineralogical studies of the Gyongyosvisonta open cast lignite mine allow further subdivisions of its profile. The occurence of crystoballite in the cover deposits indicates that the volcanic rocks in the Matra Mountains supplied the material
  • . The pedological analyses point to the common origin and similiarities in the deposition of the cover deposits. (DLO).
  • New data on the stratigraphy and pedology of the Clovis and Plainview sites, southern High Plains
  • The well known Clovis and Plainview paleo-indian sites of New Mexico and Texas have yielded new data on regional late Quaternary geologic, paleoclimatic, and pedologic histories.
  • Polish pedological studies on Spitsbergen. A review
  • A review of Polish pedological studies carried out on Spitsbergen since 1957. The first part deals with the important papers going through the sections of soil science. Special attention was focused on arctic soil forming processes, physical
  • properties (changes in soil volume, soil movements, thermal features), chemical properties and soil biology. Another part gives the lines for future pedological studies.
  • This paper furnishes new evidence of geomorphological and pedological processes taking place on the terraces of the River Guadalquivir. It deals with the formation of depressions in which blackening of soils to form Vertisols accurs
  • , with the degeneration of these soils by sand contamination, and with the existence of rubefied paleohorizons at the base of current soil profiles.
  • of this study were : 1) to assess Zr- and Ti-bearing grains as minerals resistant to chemical weathering prior to applying Zr and Ti elements in determining parent material uniformity, and 2) to confirm whether pedological processes or a lithologic discontinuity
  • may be responsible for the textural contrast within the red and black soil profiles.
