  1. 1. Resolving temporal links between the Högberget granite and the Wigström tungsten skarn deposit in Bergslagen (Sweden) using trace elements and U-Pb LA-ICPMS on complex zircons

    University essay from Lunds universitet/Geologiska institutionen

    Author : Anders Plan; [2020]
    Keywords : Bergslagen; Wigström; Högberget; geochronology; geochemistry; U-Pb; REE; trace element; zircon; hydrothermal zircon; LA-ICPMS; SEM; skarn; tungsten; wolfram; scheelite; deposit; ore; critical raw material; Earth and Environmental Sciences;

    Abstract : Combined U-Pb and REE trace element LA-ICPMS analyses were performed on zircons, from the scheelite-bearing Wigström skarn, associated micro-granitic dykes and the highly evolved parental Högberget (sensu stricto) granite. Combined systematic of zircon typology and microtextures, trace elements and isotopic chemistry suggest the presence of several diverse zircon types, spanning from early- to late- magmatic stage into a hydrothermal stage.

  3. 2. Detection of metals and trace elements in rice in Matlab, Bangladesh: A descriptive study

    University essay from Uppsala universitet/Internationell mödra- och barnhälsovård (IMCH)

    Author : Shabana Azmy; [2020]
    Keywords : Toxic metals; essential elements; rice; Matlab; Bangladesh.;

    Abstract : Rice is the staple food for almost half of the global population, including Bangladesh. This may be problematic, as rice may be contaminated with toxic metals, like arsenic (As), cadmium (Cd), lead (Pb) due to industrialization, overuse of cultivating land, fertilizers and pesticides.

  4. 3. Laser Ablation in Magnetites; Unravelling the Signatures of Trace Element Patterns for Ore Petrogenesis : Trace element signatures of magnetite linked to metallogenesis of iron mineralizations of the Kiruna type

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Siôn Kinson; [2020]
    Keywords : EPMA; LA-ICPMS; petrogenesis; magnetite; orthomagmatic; igneous; hydrothermal; alteration; EPMA; LA-ICPMS; petrogenes; magnetit; ortomagmatisk; stollande; hydrotermisk; förändring;

    Abstract : Trace element analyses of magnetite samples from multiple ore deposits worldwide have recently been conducted, using both EPMA and LA-ICPMS, in order to try and understand the petrogenesis of Kiruna-type ore deposits. Here I employ literature data and new data from Kiruna and Grängesberg (Sweden) to help constrain and visualise evolutionary trends recorded by our samples and derive an overall model for the evolutionary processes that lead to Kiruna-type deposits.

  5. 4. Askåterföring i Jämtland : biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi

    University essay from SLU/Dept. of Forest Soils

    Author : Ingegerd Backlund; [2007]
    Keywords : aska; biobränsleaska; biobränsle; GROT; Norrland; ICPMS; skog; skogsbruk; arsenik; miljökvalitetsmål;

    Abstract : Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. READ MORE
