  1. 1. Characterization of mineral parageneses and metamorphic textures in eclogite- to high-pressure granulite-facies marble at Allmenningen, Roan, western Norway

    University essay from Lunds universitet/Geologiska institutionen

    Author : Stylianos Karastergios; [2020]
    Keywords : Western Gneiss Region; Vestranden; Roan; Caledonides; marble; calc-silicate; metabasic; petrography; SEM-EDS; mineral chemistry; mineral equilibrium; P–T estimate; devolatilization; Earth and Environmental Sciences;

    Abstract : The Roan peninsula in western Norway, Vestranden, is known for exposing one of the deepest parts of the Scandinavian Caledonian orogen, similar to the Western Gneiss Region. Throughout the Roan area, eclogites and high-pressure granulite- and amphibolite-facies gneisses occur, associated with supracrustal rocks including marbles, calc-silicate rocks and amphibolites.

  3. 2. How does drainage affect hydrology and hydrochemistry in boreal peatlands?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Albin Enetjärn; [2018]
    Keywords : trenching; ditching; draining; dikning; dikningseffekter; torvmark; markavvattning;

    Abstract : Boreal peatlands are substantial terrestrial carbon storages. They are also important for the function of several large-scale cycles and systems that humanity benefits from. Drainage affects peatlands by establishing a new, lower equilibrium for the groundwater table. READ MORE

  4. 3. Relationship Between Hekla’s Magmatic System and Its Eruptive Behavior

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Eric Andin; [2017]
    Keywords : Hekla; crystal mush; thermobarometry; magma storage depth; Hekla; kristallansamling; termobarometri; magmalagringsdjup;

    Abstract : The southern part of Iceland incorporates two parallel volcanic zones, the Eastern Volcanic Zone and the Western Volcanic Zone. These two branches are connected by an E-W transform. Hekla is located close to intersection between the two plate boundaries. Hekla is one of Iceland's most active and explosive volcanoes. READ MORE

  5. 4. Geochemistry of arsenic and heavy metals in pyrite ash : speciation, solubility control mechanisms and geochemical modelling

    University essay from SLU/Dept. of Soil and Environment

    Author : Gunilla Theorin; [2015]
    Keywords : soil contamination; leaching tests; extractions; EDTA; kinetics; surface complexation modelling;

    Abstract : This thesis was part of a project at the Swedish Geotechnical Institute aiming at investigating the geochemistry of heavy metals and arsenic in pyrite ash. The spe-cific aims with this work were to extend the knowledge on solubility control mechanisms of metals in pyrite ash and how the sorption ability of the ash was dependent on content of iron (hydr)oxides.

  6. 5. Metamorphic Evolution of the Middle Seve Nappe in the Snasahögarna area, Scandinavian Caledonides

    University essay from Berggrundsgeologi

    Author : Åke Rosén; [2014]
    Keywords : ;

    Abstract : In the Snasahögarna area, situated in the central Scandinavian Caledonides, the Middle Seve Nappe Complex mainly consists of pelitic gneisses. Within these garnet and kyanite bearing gneisses the first discovery of metamorphogenic diamond in Sweden has been confirmed by micro raman spectroscopy. READ MORE
