1. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. READ MORE

2. Characterization of the cobalt content in zinc ore from Zinkgruvan, Sweden
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Zinkgruvan is a stratiform Zn-Pb-Ag deposit located in the Bergslagen ore district in south central Sweden. Elevated concentrations of cobalt have been detected in zinc ore from the mine. READ MORE

3. Geochemical and Mineralogical Comparison of XRT-XRF Scanning Technology Versus Traditional Analysis of Drill Core from the Assarel Porphyry Copper-Gold Deposit (Panagyurishte District, Bulgaria)
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Ongoing, environmental and economic matters related to mining sustainability and its impacts are leading to the search for new ways to asses and extract commodities more efficiently. A key aspect in the shift to more sustainable mining is the rapid, digital characterization of orebody mineralogy and geochemistry to help optimize the extractive process. READ MORE

4. Cr-spinels in the Franklinian Mobile Belt : a geochemical record of Paleozoic tectonics
University essay from Stockholms universitet/Institutionen för geologiska vetenskaperAbstract : The chemical compositions of Cr-spinel extracted from mafic and ultramafic rocks collected on Ellesmere Island in the Arctic Canadian Archipelago were obtained through electron microprobe analyses. The extensively altered rocks are sampled from rock units in the Franklinian MobileBelt, which is representative of a Paleozoic tectonically active oceanic regime of which little is presently known.

5. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : 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. READ MORE
