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

    University essay from Lunds universitet/Geologiska institutionen

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

    Abstract : 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. READ MORE

  3. 2. A re-investigation of hummocky moraine formed from ice sheet decay using geomorphological and sedimentological evidence in the Vomb area, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Tim Bjermo; [2022]
    Keywords : glacial geomorphology; remote sensing; LiDAR; sedimentology; glacitectonite; deformation structures; hummocky moraine; quaternary geology; deglaciation; glacial geomorfologi; fjärranalys; sedimentologi; glacitektonit; deformationstrukturer; småkullig morän; backlandskap; moränlandskap; kvartärgeologi; Earth and Environmental Sciences;

    Abstract : Glacial sediment-landform assemblages have long been used to reconstruct the dynamics of ice sheets throughout the Quaternary time period, particularly so for the period of the last glaciation in northern Europe and southern Scandinavia. One such sediment-landform assemblage is hummocky moraine, which has previously been used as an all-encompassing descriptive terminology strongly associated with dead ice meltout and passive deglaciation.

  4. 3. Geochemistry of stream plants and its statistical relations to soil- and bedrock geology, slope directions and till geochemistry : a GIS-analysis of small catchments in northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Harry Eriksson; [2017]
    Keywords : Biogeochemistry; GIS; Physical Geography and Ecosystem analysis; Geographical Information Systems; Geochemistry; Catchments; Drainage areas; Earth and Environmental Sciences;

    Abstract : Subaquatic mosses and stream plants have been recognized as suitable sample media for detection of geochemical variations in their surrounding environments. These plants were originally used in search for mineral deposits but later on also for detection of environmental pollution. READ MORE

  5. 4. TEM investigation on Challapampa aquifer, Oruro Bolivia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Måns Larsson; [2016]
    Keywords : kartering; survey geofysik; sedimentologi; geology; hydrogeology; geophysics; sedimentary; geologi; hydrogeologi; Earth and Environmental Sciences;

    Abstract : I denna studie utfördes en TEM (transient elektromagnetisk) undersökning på den Bolivianska altiplanon, norr om staden Oruro. I Oruro finns det ett underskott av dricksvatten och deras huvudsakliga vattenförsörjning kommer från aquiferen Challapampa. READ MORE

  6. 5. Diatom distribution in the lower Save river, Mozambique : Taxonomy, salinity gradient and taphonomy

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Marie Christiansson; [2016]
    Keywords : Diatoms; Quaternary geology; micropaleontology; taphonomy; taxonomy; siliceous microfossils;

    Abstract : In this study diatom distribution within the lower Save River, Mozambique, has been identified from surface sediments, surface water, mangrove cortex and buried sediments. Sandy units, bracketing a geographically extensive clay layer, have been dated with optical stimulated luminescence (OSL). READ MORE
