  1. 1. 3D modelling and resistivity measurements for hydrogeological assessments in the northern part of Vombsänkan

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Farid Khorshidian; [2023]
    Nyckelord :Conceptual 3D modelling; Resistivity; Hydrogeology; Blue Transition; Vombsänkan; Vombverket; Earth and Environmental Sciences;

    Sammanfattning : The geology of Vombsänkan is characterized by a complex sequence of Quaternary deposits overlying the Paleozoic sedimentary bedrock. The area is 759 km2 and has recorded several ice advances followed by glacial retreats and ice melting. LÄS MER

  3. 2. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ebba Pegestam; [2022]
    Nyckelord :Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Sammanfattning : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  4. 3. Structural investigation of ductile deformations across the Frontal Wedge south of Lake Vättern, southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ellinor Halvarsson; [2022]
    Nyckelord :Frontal wedge; deformation zone; Sveconorwegian orogeny; Sveconorwegian Orogen; Eastern Segment; shear-sense indicators; Protogine zone; structural geology; bedrock geology; Earth and Environmental Sciences;

    Sammanfattning : Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. LÄS MER

  5. 4. Epidotization as an Effect of Fluid Rock Interaction, Recorded by a Granitoid From Hågadalen, Uppsala

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Linn Barreby; [2022]
    Nyckelord :Fluids; Fluid Transport; Metamorphism; Metasomatism; Saussuritization; Epidote Group; Geology; Bedrock; Fluider; Fluidtransport; Metamorfos; Metasomatism; Saussuritisering; Epidot Gruppen; Geologi; Berggrund;

    Sammanfattning : A common driving mechanism of metamorphic processes, from which secondary mineralizations and structures develop in a protolith, is known to be a change of the immediate P-T environment that a rock resides in. A factor in this process, which is poorly understood, however, is how the presence of metamorphic fluids in a system, influences the alteration of primary igneous rocks. LÄS MER

  7. 5. Kusterosion på sydvästra Gotland : En undersökning i GIS och berggrundsgeologi

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Colin Andersson; Andreas Hoset; [2021]
    Nyckelord :kusterosion; Gotland; sedimentologi; GIS;

    Sammanfattning : Southwestern Gotland has a relatively diverse bedrock where both sandstone, limestone and marl areexposed. The purpose of the survey has been to investigate differences in coastal erosion regarding thecontent of the bedrock. LÄS MER
