  1. 1. 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

  2. 2. Tracing the Origin of Metasedimentary Rocks in the Faroe-Shetland Basin

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sarah Eriksson; [2016]
    Keywords : Faroe-Shetland basin; Isotope correlation; metasediments; element analysis; Färö-Shetland bassängen; isotopkorrelation; metasediment; geokemisk analys;

    Abstract : The Faroe-Shetland region has been exposed to a long history of tectonic events and the geology in the area is rather complex. This history has led to the formation large metasedimentary deposits, though the origin of these deposits is not yet fully understood. Possible source areas are Greenland, Norway and Scotland.

  3. 3. REE mineralisation and metasomatic alteration in the Olserum metasediments

    University essay from Lunds universitet/Geologiska institutionen

    Author : Wayne Fullerton; [2014]
    Keywords : metasediment; metasomatism; mineralisation; monazite; Olserum; REE; xenotime; Earth and Environmental Sciences;

    Abstract : The Olserum mineralisation is situated in the metasediments of the Västervik formation, which repre-sents the southernmost continental margin of the Svecokarelian Domain. After deposition between 1.88 – 1.85 Ga these sediments were subsided to a depth of about 10 km and intruded by a series of granitoid melts. READ MORE

  4. 4. Basalt and Andesite Magma Storage and Evolution in Puyehue Volcano (40.5 °S), Chile

    University essay from

    Author : Joaquim Otero; [2013]
    Keywords : Volcano; Thermobarometry; Puyehue; Basalt; Andesite; Contamination;

    Abstract : The study of magmatic processes and their location in the crustal profile is fundamental for the understanding of the volcanic systems and their associated hazards. Changes and continuities in magma storage zones, fractional crystallization and crustal contamination are studied over a time span of 300 ka in Puyehue Volcano in the Southern Volcanic Zone, Chile.

  5. 5. Monazite in metasediments from Stensjöstrand : a pilot study

    University essay from Lunds universitet/Geologiska institutionen

    Author : Andreas Olsson; [2013]
    Keywords : pilot study monazit; Stensjöstrand; Sveconorwegian orogen; monazite; metasediments; metasediment; Sveconorvegiska orogenesen; pilotstudie; Earth and Environmental Sciences;

    Abstract : Monazit är ett Ree– och Th-bärande fosfatmineral som förekommer i vissa magmatiska och metamorfa bergarter. Mineralet är användbart för datering av den metamorfa utvecklingen och kan bidra till att yt-terligare karaktärisera metamorfosen i en bergart, detta genom att man undersöker zoneringar i kristallerna.
