  1. 36. Near-surface stratigraphy of till and glacifluvium near Knaften, northern Sweden : Identifying small-scale stratigraphy using ground-penetrating radar

    University essay from Institutionen för ekologi, miljö och geovetenskap

    Author : Holger Jacobson; [2013]
    Keywords : Ground-penetrating radar; small scale; near surface; stratigraphy; late Weichselian; grain-size comparison;

    Abstract : The aim of the study was to assess the possibilities in using ground-penetrating radar to identify small-scale stratigraphy in the upper 1 m of a soil profile and to statistically identify differences in the stratigraphic units discovered using the GPR unit. The study area is ca 15 km southwest of Lycksele near a gravel pit on the banks of Örån. READ MORE

  3. 37. Ice advance-retreat sediment successions along the Logata River, Taymyr Peninsula, Arctic Siberia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Martin Bernhardson; [2013]
    Keywords : Sibirien; Tajmyrhalvön; Weichselian glaciation; Ice advance-retreat stages; Russia; Taymyr Peninsula; Siberia; Ryssland; isframstötar-isreträtter; Weichselistiden; Earth and Environmental Sciences;

    Abstract : A number of sites were investigated in river sections along the Logata River on the Taymyr Peninsula, Russia, and its adjacent areas to shed more light on the glaciation history over the last glacial cycles. The sediments exposed at the investigated sites are correlated and put into a local stratigraphic scheme divided into five main units. READ MORE

  4. 38. A sedimentological and stratigraphical study of Veiki moraine in northernmost Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Þorbjörg Sigfúsdóttir; [2013]
    Keywords : Veiki moraine; glacial geology; Weichselian glaciation; northern Sweden; supraglacial lakes; Veikimorän; glacialgeologi; Weichselistiden; norra Sverige; supraglacial sjö; Earth and Environmental Sciences;

    Abstract : Veiki moraine is a landform area consisting of rim-ridged subcircular hummocks and plateaus with depressions in between, mostly located within a N-S extending zone of a hummocky landscape. It is believed to have formed during the pre-late Weichselian and survived overriding by ice during the subsequent glaciations. READ MORE

  5. 39. Peat stratigraphical study of hydrological conditions at Stass Mosse, southern Sweden, and the relation to Holocene bog-pine growth

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linda Adamsson; [2013]
    Keywords : tall; mosse; klimatförändringar; palaeoecology; macrofossil analysis; pines; climate change; bog; makrofossilanalys; paleoekologi; Earth and Environmental Sciences;

    Abstract : Sammanfattning: Torvhorisonter med stora mängder subfossila stubbar och rötter av tall (Pinus sylvestris) förekommer ofta i nordeuropeiska torvmossar. De visar att mossarna varit tallbevuxna under delar av Holocen. READ MORE

  6. 40. Stratigraphy, facies and depositional history of the Colonus Shale Trough, Skåne, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Magnus Eriksson; [2012]
