  1. 11. 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

  3. 12. Petrography, alteration and structure of the Bronäs Zn-Pb-Ag deposits, Bergslagen, Sweden

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

    Författare :Tom Turner; [2020]
    Nyckelord :Bronäs; Sala;

    Sammanfattning : This report aims to characterize the alteration styles and mineralization of the Zn-Pb-Ag Bronäs deposit, in the Sala area of the Bergslagen mining district, Sweden.  It presents data collected through 237m of lithological logging and subsequent lithogeochemical data, which, coupled with thin section and SEM analysis has led to the first geological descriptions of the rocks in the deposit.

  4. 13. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

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

    Författare :Filip Ivarsson; [2019]
    Nyckelord :Zinkgruvan; Bergslagen; Magnetite; REE; Broken Hill-type; Skarn; SEDEX;

    Sammanfattning : Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. LÄS MER

  5. 14. Utveckling av Reglersystem för ett Labyrintspel : Modellbaserad design i praktiken

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Mikael Nådin; Kristian Ericsson; [2019]
    Nyckelord :Automatic Control Systems; Labyrinth Game; Modelbased design;

    Sammanfattning : This thesis evaluates two automatic control systems, PID and LQ, for the purpose of controlling the steel marble in a Brio labyrinth game. The objective has been for these automatic control strategies to bring the marble through the labyrinth and examine how well they handle this problem. LÄS MER

  7. 15. The long-term effects of Underwater Archaeological Parks on the Preservation of Underwater Cultural Heritage. An Overview

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Konstantina Oikonomopoulou; [2018-06-27]
    Nyckelord :underwater cultural heritage; in situ preservation; informational preservation; degradation; diving parks;

    Sammanfattning : The 2001 UNESCO Convention on the Protection of Underwater Cultural Heritage (UCH) indicates preservation in situ as a first option and encourages public access unless it is incompatible with protection and management. Protection methods address natural factors that include environmental conditions and microorganisms, and human impact, direct or indirect. LÄS MER
