The age of Glacier Peak tephra in west-central Montana
  • Mountains ; Sheep Mountain Bog ; Tardiglaciaire ; Tephra ; Tourbière ; Téphrochronologie
  • At Sheep Mountain Bog, near Missoula, Montana a late-glacial tephra, that probably fell in late summer, is preserved in lake deposits. Sediment surrunding the ash was 14C dated to about 11,200 yr B.P. Electron-microprobe analyses of the volcanic

A Neolithic yew bow in the Polish Carpathians : evidence of the impact of human activity on mountainous palaeoenvironment from the Kamiennik landslide peat bog
  • A Neolithic yew bow in the Polish Carpathians : evidence of the impact of human activity on mountainous palaeoenvironment from the Kamiennik landslide peat bog
  • Artifact ; C 14 dating ; Carpathian Mountains ; Flysch ; Holocene ; Human impact ; Landslide ; Mountain ; Neolithic ; Palaeo-environment ; Peat bog ; Poland
  • A unique artefact, the fragment of a bow made of yew wood, indicating the hunting activity of prehistoric man, was found within the sediments of the landslide peat bog (at the depth of 330 cm) formed on the Mt. Kamiennik (Polish Flysch Carpathians
Soil carbon and nitrogen across wetland types in discontinuous permafrost zone of the Xiao Xing'an Mountains, northeastern China

  • In this study, the AA. collected soil samples from different wetlands in the discontinuous permafrost zone of the Xiao Xing'an Mountains, northeastern China. Permafrost was only present in the bogs and fens in this zone. Soil C concentrations were
  • processes under future global warming scenarios. However, the soil C storage and total N storage were not significantly difference in the upper soil layer for the wetlands types. The vegetation changing of bogs and fens would increase the depth

  • Pollen, macrofossil (logs and needles), and oxygen-isotope data from tree-rings are presented for three alpine bog sites in the Maligne Range of the Canadian Rockies.
Climatic and anthropogenic influences on radial growth of scots pine at Hanvedsmossen, a raised peat bog, in south central Sweden
  • Climatic and anthropogenic influences on radial growth of scots pine at Hanvedsmossen, a raised peat bog, in south central Sweden
  • Dendrochronology ; Dendrology ; Drainage ; Human impact ; Palaeobiogeography ; Palaeoclimate ; Peat bog ; Sweden
  • Past studies of the climatic influence on tree growth at peat bogs in northern latitudes have shown weak correlation between annual tree-ring widths and climatic parameters during the growing season. At Handvedsmossen, a raised peat bog in south
  • central Sweden, tree-ring width chronologies from one drained and one undrained growth site, as well as one dry site outside the bog, were compared to meteorological records.

The importance of topographic factors on the distribution of bog and heath in a Newfoundland blanket bog complex
  • The importance of topographic factors on the distribution of bog and heath in a Newfoundland blanket bog complex
  • Canada ; Ecosystem ; Geographical information system ; Humid environment ; Newfoundland ; Numerical model ; Peat bog ; Photogrammetry ; Quantitative analysis ; Soil water ; Topography
  • Three blanket bog sites on the southeastern lobe of the Avalon Peninsula, Newfoundland, were studied. Terrain shape characteristics such as slope, plan and profile curvature, and upslope catchment area were derived from digital elevation models
  • of surface and mineral substrate, and analysed using Partition d'un Ensemble Géographique pour l'Analyse Spatiale Ecologique (PEGASE). Although lower elevations were more favourable for bog development, bog communities persisted in upper elevations in areas

  • A hazai tozeglapok (tozegek) osztalyozasa. (The classification of local peat-bogs peats)
  • The classification serves both the protection and the various utilization of peat-bogs all the more unless top urgent steps are taken in 30-50years they disappear in Hungary. (CK).
Mineralogy of Holocene bog-iron ore in northern Belgium
  • Mineralogy of Holocene bog-iron ore in northern Belgium
  • Goethite, siderite, ferrihydrite, oxidized blue vivianite and a practically X-ray amorphous oxidation product of vivianite were identified as the dominant iron components of the bog-iron ores.

A 8000years old pine trunk from Dovre, South Norway
  • A well preserved pine trunk, 3-4m long and 0,3m thick, sticking out of a bog situated about 1010m above sea-level, in the now almost treeless area above Nysetra on the Dovre plateau, has been dated at 8240100years B. P. This great age corresponds
  • well with the results obtained from other regions in Norway and also the Sylarna-Ovik mountains in Sweden, showing that pine reached its highest post-Weichselian altitude and widest distribution just before 8000 B. P. (IMB).
Sponge gemmules from lake sediments in the Puget Lowland, Washington
  • Gemmules of five species of freshwater sponge found in deposits at Cedar Mountain bog in the southeaster Puget Lowland were used to infer that during the late-glacial period the water was calcareous, was not deficient in SiO, was aerobic, and had
