  1. 1. Internal geology and emplacement processes of Kimberlites, Case Study from the Tsabong Kimberlite Field, Botswana

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Mpho Ndebele; [2020]
    Nyckelord :Kimberlites; Geology; Emplacement Processes; Botswana;

    Sammanfattning : The Crateceous (85 Ma) MK1 pipe is part of the Tsabong kimberlite cluster located approximately550km south west of Gaborone and geologically found within the Kapvaal Craton. The Tsabongkimberlite field consists of 86 known kimberlites. The MK1 pipe is the largest of this cluster at 140ha,1. LÄS MER

  2. 2. Processes of lateral moraine formation at a debris-covered glacier, Suldenferner (Vedretta di Solda), Italy

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Monika Rabanser; [2019]
    Nyckelord :Lateral moraines; Moraine genesis; Moraine stability; Debris-covered glaciers; Clast shape; Alps; Sedimentology; Glacier fluctuations; Earth and Environmental Sciences;

    Sammanfattning : Lateral moraines are key features of glacial landscapes in high-alpine mountain areas. Research on lateral moraine formation is mostly limited to clean-ice glaciers; lateral moraine formation at the margins of debris-covered glaciers is currently poorly understood in an Alpine and sedimentological context.

  3. 3. Petrophysical and GeophysicalAnalysis of Ordovician Limestone Mounds for the Purpose of Hydrocarbon Reservoir Exploration : Petrofysisk och geofysisk analys av Ordoviciska kalkstensstrukturer för hydrokarbonprospektering

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Felix Söderberg; [2015]
    Nyckelord :Gotland; hydrocarbons; Ordovicium; mounds; reefal structures; Hydrokarbon; revstruktur; slamhög; ordovicium; Gotland;

    Sammanfattning : Gripen Oil & Gas have extended their prospecting license on Gotland to the north end of the island to search for potential hydrocarbon reservoirs. Earlier prospecting has shown that limestone mound structures from Ordovicium have high potential as hydrocarbon reservoirs due to their antiformal shape and the petrophysical properties of the limestone.

  4. 4. Lithofacies analysis and heterogeneity study of the subsurface Rhaetian-Pliensbachian sequence in SW Skåne and Denmark

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Samer Bou Daher; [2012]
    Nyckelord :Sorgenfrei-Tornquist Zone; Höllviken Halfgraben; Rhaetian; Hettangian; Sinemurian; Pliensbachian; sequence stratigraphy; lithofacies; reservoir; geothermal; CO2 storage; Sorgenfrei- Tornquistzonen; Höllvikensänkan; sekvensstratigrafi; reservoar; geotermisk; CO2-lagring; Earth and Environmental Sciences;

    Sammanfattning : The geological setting of Skåne is the outcome of successive phases of transtensional tectonics, block-faulting, subsidence, transpression and inversion focused around the Sorgenfrei-Tornquist Zone. The Höllviken Halfgraben is one of the major blocks in southwestern Skåne with a Rhaetian–Pliensbachian succession characterized by interbedding of arenaceous and argillaceous facies of local and regional extent.

  5. 5. Sequence stratigraphy, palynology and biostratigraphy across the Ordovician-Silurian boundary in the Röstånga-1 core, southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ahmed Salah Badawy; [2012]
    Nyckelord :avsättningsmiljöer; stratigrafi; Sweden; Scania; Röstånga; Silurian; Ordovician; TAI; Thermal Alteration Index; palynology; sea level changes; stratigraphy; depositional environments; havsnivåförändringar; palynologi; Ordovicium; Silur; Skåne; Sverige.; Earth and Environmental Sciences;

    Sammanfattning : A multiproxy study on sedimentary rocks spanning the Ordovician-Silurian boundary has been performed on material from the Röstånga-1 core, with the aims to improve the biostratigraphical and sedimentological framework and to interpret the depositional environment during this interval in Earth’s history. The sedimentary succession in the Röstånga-1 core is developed in the Scanian Lithofacies Belt and is considered an excellent upper Middle Ordovician-Lower Silurian reference section for southernmost Sweden.
