  1. 1. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Per Wahlquist; [2023]
    Nyckelord :volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

    Sammanfattning : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

  3. 2. Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hanna Kervall; [2021]
    Nyckelord :EGS; deep drilling; geothermal; petrology; petrophysical properties; Sveconorwegian; Earth and Environmental Sciences;

    Sammanfattning : The ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E. LÄS MER

  4. 3. Radiogenic Dating and Microstructure Analysis of Shear Zones Found Within the Seve Nappe Complex in the Åre Region, Jämtland, Scandinavian Caledonides

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Cameron Alessandrini; [2017]
    Nyckelord :Rb-Sr dating; Ar-Ar dating; Lower Seve Nappe; Scandinavian Caledonides; COSC drillhole.; Rb-Sr datering; Ar-Ar datering; Seveskollan; skandinaviska Kaledoniderna; vit glimmer; COSC borrkärna.;

    Sammanfattning : The North Atlantic Caledonides are a continent-continent collision type orogeny found in WesternScandinavia, Svalbard, Greenland and the British Isles. They are thought to have formed as a result of a complex history consisting of repeated ocean opening and closure. LÄS MER

  5. 4. The Birimian event in the Baoulé Mossi domain (West African Craton) : regional and global context

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Mikael Grenholm; [2014]
    Nyckelord :accretionary orogen; Atlantica; Birimian event; supercontinent cycle; Lomagundi-Jatuli event; Earth and Environmental Sciences;

    Sammanfattning : The crystalline basement of the West African Craton (WAC) was established during the Siderian to Orosirian (circa 2.35-1.95 Ga) Birimian event through accretion of extensive tracts of juvenile crust that was tectonically juxtaposed with Archean cratons. LÄS MER

  7. 5. Oil occurrences in crystalline basement rocks, southern Norway : comparison with deeply weathered basement rocks in southern Sweden

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Linnéa Gunterberg; [2013]
    Nyckelord :deep weathering; petroleum; crystalline basement; saprolite; kristallin berggrund; djupvittring; Earth and Environmental Sciences;

    Sammanfattning : Ökande oljepriser och en stigande efterfrågan gör idag undersökningar av alternativa petroleumreservoarer extra intressanta. Istället för att borra i den sedimentära berggrunden ges nu möjligheten att granska kristallina berggrundsreservoarer. LÄS MER
