  1. 6. A geophysical survey (TEM; ERT) of the Punata alluvial fan, Bolivia

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Joakim Mårdh; [2017]
    Nyckelord :electromagnetic; geophysics; TEM; Punata; alluvial fan; Earth and Environmental Sciences;

    Sammanfattning : The Punata alluvial fan, situated in central Bolivia (Valle Alto) between the Altiplano and the lowlands, is an important aquifer for the local rural population. Due to rapid development and population growth in the area, the demand for fresh water has increased in recent year. LÄS MER

  2. 7. Depositional history of the Neoproterozoic Visingsö Group, south-central Sweden

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Viktor Ahrenstedt; [2017]
    Nyckelord :sedimentology; depositional history; Visingsö Group; Neoproterozoic; Earth and Environmental Sciences;

    Sammanfattning : The Neoproterozoic sedimentary rocks of the Visingsö Group are one of few remaining rocks from this time. They provide a vital clue to understanding how the landscape looked at this time. The various environmental factors that prevailed and affected deposition are key to paint a bigger picture. LÄS MER

  3. 8. Sedimentological study of the Jurassic and Cretaceous sequence in the Revinge-1 core, Scania

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Casandra Hajny; [2016]
    Nyckelord :Jura; Krita; Vomb; Fyledalen; Vitabäck; Arnagergrönsand; Mollusker; Bivalver; Palynologi; Biostra-tigrafi; Vulkanism; Pyrit; Järnooider; Jurassic; Cretaceous; Vomb Trough; Vitabäck Clay; Fyledal Clay; Arnager Greensand; Molluscs; Bivalves; Palynology; Biostratigraphy; Volcanism; Pyrite; Iron ooids; Earth and Environmental Sciences;

    Sammanfattning : This thesis presents a study of the core from the Revinge-1 borehole from the Vomb Trough. The core displays strata from the Upper Jurassic to the Upper Cretaceous including strata covering the the J/K−boundary . LÄS MER

  4. 9. Characterization of an REE-enriched black substance in fractured bedrock in the Ytterby Mine

    Magister-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Susanne Sjöberg; [2014]
    Nyckelord :;

    Sammanfattning : A black substance seeping from fractured bedrock was observed in tunnels leading to the mainshaft of the Ytterby mine on Resarö, Sweden. These are dry tunnels at shallow depth, +5 mabove sea level and 29 m below ground surface, resulting from the reconstruction of the mineinto a fuel deposit for the Swedish Armed Forces during the Cold War era.

  5. 10. Upper slope sedimentation environments in the Gaoping river-sea system of SW Taiwan

    Kandidat-uppsats, Institutionen för geologiska vetenskaper

    Författare :Lina Hansson; [2013]
    Nyckelord :Marine geology; sediment; Pb210; Grain size; Taiwan; hyperpycnal;

    Sammanfattning : The Gaoping Slope, off the south west coast of Taiwan, is a tectonically active sedimentation environment attaining most of its sediment from the Gaoping River. This study examines sediment cores from two localities at 375 m and 495 m water depth by using X-radiography, Grain size- and 210Pb analysis, with the purpose of comparing the sedimentation environment at the two sites and examine how they were both affected by high sediment delivery during typhoon Morakot.
