  1. 1. Magma-Carbonate Interaction and CO2 Release: A Case Study from Carlingford Igneous Centre, Ireland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emelie Lagrosen; [2020]
    Nyckelord :Magma-carbonate interaction; CO2; calc-silicate; skarn; marble; Carlingford; SEM-EDX; XRF; LA-ICP-MS; Magma-karbonat-interaktion; CO2; kalk-silikat; skarn; marmor; Carlingford; SEM-EDX; XRF; LA-ICP-MS;

    Sammanfattning : Magma which intrudes into carbonate rich crust, interacts with the carbonate in several ways, for example by contact metamorphism and formation of marble or by metasomatism resulting in calc-silicate skarn. These processes release volatiles, such as CO2, from the carbonate and might thus cause climate change. LÄS MER

  2. 2. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Chen Luo; [2020]
    Nyckelord :acid mine drainage; arsenic; cadmium; geochemical modeling; heavy metals; lead; principal component analysis;

    Sammanfattning : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.

  3. 3. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Eva Smedborn Pausson; [2019]
    Nyckelord :;

    Sammanfattning : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

  4. 4. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Niklas Gunnarsson; [2019]
    Nyckelord :Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Sammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER

  5. 5. Vik för vik – Mot en friskare Östersjökust med fokus på Strandstuviken

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Isak Nyborg; [2019]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Eutrophication is a serious problem that is affecting the Baltic Sea and its streams connecting to it. It brings a negative impact on the biodiversity, the streams recreational value, sport fishing and also the overall ground water quality. LÄS MER
