  1. 1. Silver Mineralogy and Modes of Occurrence at the Silver Hart Deposit, South East Yukon.

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

    Författare :Michael Ives-Ruyter; [2023]
    Nyckelord :Canada; Yukon; silver; lead; zinc; galena; sulfosalt; sulfur isotope;

    Sammanfattning : The Silver Hart property is a high grade silver-lead-zinc deposit consisting of polymetallic vein style, manto (carbonate replacement) style, and skarn type mineralization. Host rock consists of calcareous and non-calcareous sediments of the Cassiar Platform, mainly biotite schists, limestone units, and the monzogranite unit of the Cassiar Batholith. LÄS MER

  3. 2. Factors governing marble lightness in peripheral alteration haloes around carbonate-hosted Zn-Pb-Ag-(Cu-Au) deposits, Garpenberg, Sweden

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

    Författare :Marcus Eriksson; [2020]
    Nyckelord :Carbonate; Zn; Pb; Ag; Cu; Au; Alteration haloes; marble; lightness; Bergslagen; Garpenberg;

    Sammanfattning : A Master thesis about the Garpenberg deposit located in Bergslagen, a lithotectonic domain, with a mining history that might date back as far as 350 BC. Marble- and skarn-hosted sulfide deposits are found in the area, which creates the opportunity to mine both limestone and sulfidic ore in a single mine. LÄS MER

  4. 3. 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

  5. 4. 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.

  7. 5. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Dino Leopardi; [2020]
    Nyckelord :Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

    Sammanfattning : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. LÄS MER
