1. 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
2. Undersökning av lakningspotential och kristallareafördelning av opaka mineral i bergarter från Ekobacken, Värmdö kommun
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Ekobacken, Värmdö kommun, har problem med surt yt- och grundvatten med höga metallhalter. Uppmärksamheten har riktats mot berggrunden som krossats och lagrats i deponihögar. Bildningen av sur lak styrs av flertalet geokemiska egenskaper, bland annat vilka sulfidmineral som förekommer och deras kristallstruktur. LÄS MER
3. Increased leaching of metals as a result of foundation work
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Heavy metal contamination in the environment is a global issue that is likely to increase in the future. This report investigates a construction area in which increased concentrations of the heavy metals cadmium, cobalt, copper, nickel and zinc and a decreased pH-value has been observed in the surface water recipient.

4. Mineraliseringar utmed REE-linjen i sydvästra Bergslagen
Kandidat-uppsats, Uppsala universitet/BerggrundsgeologiSammanfattning : This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. LÄS MER
5. Kadmium i berg, jord och mineral - förekomst och påverkan på den nära omgivningen
Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : This report covers a survey of the natural occurence of the heavy metal cadmium (Cd) in soil and bedrock in Skåne, Sweden and Europe. The main focus is on the cadmium concentrations in samples of sphalerite (ZnS) collected in quarries in Skåne during the study, and in samples of sphalerite from the rest of Sweden and locations in Spain and USA depostited by the Department of Geology, Lund University.
