  1. 1. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Skoog; [2022]
    Keywords : Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

    Abstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

  3. 2. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ida Sundblom; [2022]
    Keywords : sulfide-bearing rock; acid rock drainage; sulfide oxidation;

    Abstract : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. READ MORE

  4. 3. GEOCHEMICAL UNDERSTANDING OF VANADIUM IN MALMBERGET ORES (KIRUNA TYPE), NORTHERN SWEDEN

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

  5. 4. Structural analysis of the hinge region of the Islay Anticline.

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Elin Rydeblad; [2016]
    Keywords : Geology; structural geology; Islay; anticline; fluid flow;

    Abstract : The hinge region of a major anticlinal fold structure in the SW Scottish Highlands was located in the eastern part of the Isle of Islay. The structure plunges gently NNW, with the hinge line measuring 02/026. READ MORE

  6. 5. 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.
