1. 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 naturresurserSammanfattning : 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
2. Mineralogical and Geochemical characterization of the Fe-Cu-Occurrence and associated Hanging wall and Footwall Alteration halo of the Viscaria D-Zone, Kiruna District, Northern Sweden
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : Northern Norrbotten County is one of the three major ore producing districts in Sweden. Based on the predominance of epigenetic Cu-Au and Fe-oxide mineralization this region is regarded as a typical IOCG province. The massive to layered Viscaria Cu-deposit is proposed to be a VMS deposit of Besshi-type and is unique in deposit type of the region. LÄS MER
3. Metamorphosed and partially molten hydrothermal alteration zones of the Akulleq glacier area, Paamut gold province, South-West Greenland
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Området kring akulleqglaciären ligger i närheten av bosättningen Paamiut, sydvästra Grönland. Tonalit- trondhjemit och granodioritgnejser (TTG) utgör huvudlitologin i området. Inom TTG-gnejserna återfinns ett cirka 1 km brett hästskoformat bälte av suprakrustala bergarter. LÄS MER
