  4. 3. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Jens Henriksson; [2022]
    Keywords : Kiruna-type deposit; electron backscattered diffraction; crystal settling; Fe-O systematics; crystal alignment;

    Abstract : European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. READ MORE

  6. 5. Phosphorus accumulation in constructed wetlands : A study of 10 wetlands constructed on agricultural clay soils in Södermanland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Gabriella Corbee; [2021]
    Keywords : Phosphorus retention; sedimentation; hydraulic load; Fosforavskiljning; sedimentation; hydraulisk belastning;

    Abstract : Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. READ MORE
