    Abstract : The physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. READ MORE

  4. 2. From growth cessation to bud burst : conifer seedling development in response to nursery culture and environmental stimuli

    Author : Elisabeth Wallin; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Picea abies; Pinus sylvestris; Pseudotsuga menziesii; seedling status; gene activity; photoperiod; storability; vitality; transplants; shoot electrolyte leakage; Picea abies; Pinus sylvestris; Pseudotsuga menziesii; plantstatus; genaktivitet; fotoperiod; lagringsbarhet; vitalitet; omskolningsplantor; elektrolytiskt läckage; Energy and Built Environments; Energi och samhällsbyggnad;

    Abstract : In Sweden, 350-400 million seedlings are produced annually for forest regeneration. About one third of these are overwintered in frozen storage, necessitating accurate methods to assess storability. Young transplants of Norway spruce (Picea abies (L.) Karst. READ MORE

  5. 3. Late Ordovician-Early Silurian facies development and stratigraphy of Jämtland, central Sweden

    Author : Peter Dahlqvist; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biostratigraphy; Sedimentology; Stratigrafi; Stratigraphy; Paleontologi; Palaeontology; Jämtland; provenance; brachiopods; conodonts; Hirnantian; Silurian; Ordovician; glaciation; eustasy; Sedimentologi; sedimentology;

    Abstract : This thesis is based on studies of Lower Palaeozoic sedimentary successions within the central Scandinavian Caledonides. These deposits have been transported by considerable nappe displacement (several kilometres), and are today relatively isolated from the nearest coeval outcrops (Dalarna 250 km, Oslo Region 350 km).

  6. 4. Sediment sources and transport pathways, Lithuanian coastal zone

    Author : Milda Kairytè; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment; grain size; mineralogy; Lithuania; coastal zone; provenance; geology;

    Abstract : This thesis presents an investigation of recent sediments of the Lithuanian coastal zone, SE Baltic Sea. The main focus is upon the detailed documentation of grain size and mineralogy and the development of analytical methods using these essential and most common sediment parameters. READ MORE

  7. 5. Assessing the reliability of detrital zircon in Early-Earth provenance studies

    Author : Ross Kielman; Martin Whitehouse; Alexander Nemchin; Victoria Pease; Marlina Elburg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geology; geologi;

    Abstract : Our understanding of the Early Earth and the processes that have shaped its evolution have spawned predominantly from the geochemical and isotopic signatures of a small number of zircon populations around the world. Studies of trace element distributions, Hf and O isotope systematics as well as mineral inclusion chemistry in detrital zircon are combined with U-Pb chronology in order to constrain source rock characteristics.
