  1. 1. Kan dagvatten förorena vattentäkten i Hurva?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Johan Andersson; [2019]
    Nyckelord :groundwater; storm water; till; groundwater modelling; Earth and Environmental Sciences;

    Sammanfattning : Groundwater is one of our most important natural resources. Therefore, it is important to monitor the groundwater and to protect it from pollution. At Hurva, southern Sweden, the local drinking water is produced by groundwater extraction. LÄS MER

  3. 2. U-Pb baddeleyite dating of intrusions in the south-easternmost Kaapvaal Craton (South Africa) : revealing multiple events of dyke emplacement

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Emilie Larsson; [2015]
    Nyckelord :U-Pb; baddeleyite; Kaapvaal Craton; mafic dykes; geochronology; Earth and Environmental Sciences;

    Sammanfattning : This study presents U-Pb baddeleyite ages for five dolerite dykes and one sill in the Mesoarchean granitic basement of south-easternmost Kaapvaal Craton in northern KwaZulu-Natal, South Africa. The oldest dyke is ENE-trending, and is dated to 2729 ± 5 Ma. LÄS MER

  4. 3. Inventering av sprickmineraliseringar i en del av Sorgenfrei-Tornquistzonen, Dalby stenbrott, Skåne

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Jenny Halling; [2015]
    Nyckelord :Sorgenfrei-Tornquistzonen; sprickmineral; sprickgenerationer; SEM; Dalby stenbrott; Earth and Environmental Sciences;

    Sammanfattning : Sorgenfrei-Tornquistzonen har sedan slutet av Paleozoikum undergått upprepade deformationsfaser, både extensiva och kompressiva som resulterat i omfattande blockförkastningar och bassänginversion. Detta har skapat en mycket uppsprucken berggrund som med tiden läkts av olika mineral. LÄS MER

  5. 4. U-Pb baddeleyite geochronology and geochemistry of the White Mfolozi Dyke Swarm : unravelling the complexities of 2.70-2.66 Ga dyke swarms on the eastern Kaapvaal Craton, South Africa

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Johan Rådman; [2014]
    Nyckelord :Kaapvaal Craton; White Mfolozi Dyke Swarm; geochronology; U-Pb; baddeleyite; Diabase; Dolerite; geokronologi; baddeleyit; Earth and Environmental Sciences;

    Sammanfattning : Numerous mafic dykes of different generations and trends intrude the eastern part of the Kaapvaal Cra-ton. On eastern Kaapvaal, there are three previously investigated dyke swarms that appear to radiate out from the eastern lobe of the Bushveld Complex. The NE- and E trending branches comprise dykes dated at ca. LÄS MER

  7. 5. Från hav till land : en geologisk beskrivning av Skrylle

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Sammanfattning : Skrylle is a popular recreation area situated between Södra Sandby and Dalby in the Municipality of Lund. It covers an area of roughly 27 km2 and comprises 10 reserves and one national park, Dalby Söderskog. The area presents a mixture of forests and pastures on the northwestern part of Romeleåsen.
