  1. 1. Thermal history of the Phanerozoic sedimentary succession of Skåne, southern Sweden, and implications for applied geology

    University dissertation from Department of Geology, Lund University

    Author : Ingela Olsson; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Petrology; organic matter reflectance; organic geochemistry; illite crystallinity; clay mineralogy; thermal history; Phanerozoicum; Skåne; Sweden;

    Abstract : Post-depositional thermal conditions have been investigated throughout the Phanerozoic sedimentary succession in Skåne. Clay mineralogy and illite crystallinity have been the main tools for the Lower Palaeozoic strata. Within the Mesozoic sequence thermal influence was examined using RockEval pyrolysis and vitrinite reflectance analysis. READ MORE

  2. 2. Reconstruction of Holocene atmospheric mineral dust deposition from raised peat bogs in south–central Sweden

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Jenny Sjöström; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mineral dust; paleodust; peat; Sweden; Holocene; mineralogy; XRD;

    Abstract : Atmospheric mineral dust plays a dynamic role in the climate system acting both as a forcing and a feedback mechanism. To date, the majority of paleodust studies have been conducted on marine sediments or polar ice cores, while terrestrial deposition has been less studied. READ MORE

  3. 3. The Stollberg ore field - petrography, lithogeochemistry, mineral chemistry, and ore formation

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Magnus Ripa; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metamorphic; exhalative; hydrothermal; volcanogenic; skarn; magnetite; galena; sphalerite; Sweden; Bergslagen; Paleoproterozoic; deposit; mineralogy; geochemistry; Petrology; Petrologi; mineralogi; geokemi;

    Abstract : The Paleoproterozoic Fe-Pb-Zn-Mn(-Ag) Stollberg deposit is situated in the Bergslagen region of south-central Sweden. 6.65 Mt of sphalerite, galena and manganiferous skarn magnetite ore occur as disseminations and semi-massive to massive ore bodies hosted by volcanogenic sediments and carbonate rocks.

  4. 4. Bringing predictability into a geometallurgical program An iron ore case study

    University dissertation from Luleå : Luleå University of Technology

    Author : Viktor Lishchuk; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additivity; Apatite iron ore; AIO; Block model; Change of support; Classification; Data integration; DT; Feed quality; Geometallurgical program; Geometallurgy; Iron ore; Iron recovery; Leveäniemi; Liberation; Machine learning; Magnetic separation; Malmberget; Mineralogical approach; Mineralogy; Prediction; Proxies; Proxies approach; Sampling; Simulation; Synthetic ore body; Traditional approach; WLIMS; Mineral Processing; Mineralteknik;

    Abstract : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. READ MORE

  5. 5. Sediment sources and transport pathways, Lithuanian coastal zone

    University dissertation from Göteborg : University of Gothenburg

    Author : Milda Kairytè; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment; grain size; mineralogy; Lithuania; coastal zone; provenance; geology;

    Abstract : This thesis presents an investigation of recent sediments of the Lithuanian coastal zone, SE Baltic Sea. The main focus is upon the detailed documentation of grain size and mineralogy and the development of analytical methods using these essential and most common sediment parameters. READ MORE
