1. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. LÄS MER
2. Samband mellan geologiska och bergmekaniska egenskaper i bergmaterial som bärlager till riksväg 51 : Riksväg 51 sträckan Svennevad - Kvarntorpskorset
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : This thesis was created to ensure the quality of the rock which would be crushed to base layer construction material, in a road cut at Swedish highway 51, and to find a possible link between the rock's abrasion resistance and its mineralogy. Rock samples were collected, and among other things, several ball mill tests were carried out. LÄS MER
3. Critical Assessment of the Mineralogical Collections at Uppsala University using Raman Spectroscopy
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The technique of Raman spectroscopy was applied in order to identify and characterize the number of minerals in the mineralogical collection at the Department of Earth Sciences. The collection was broadened with five rare carbonates borrowed from the collection of the Swedish Museum of Natural History in Stockholm. LÄS MER
4. Geophysical and hydrogeological survey in a part of the Nhandugue River valley, Gorongosa National Park, Mozambique : area 2 and 3
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Gorongosa National Park in central Mozambique is situated at the southernmost extension of the East African Rift System (EARS), the Urema Rift. The park is protecting a vast ecosystem of floodplains, grasslands and woody coverage. LÄS MER
5. Metamorphic study of metasediment from the Kangilinaaq Peninsula, West Greenland
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Nagssugtoqidian Orogen is represented by an approximately 300 km wide Palaeoproterozoic deformation and metamorphic belt that stretch through the southern and middle parts of west Greenland. The Orogen is characterized and dominated by metamorphosed Archaean orthogneisses with minor supracrustal sequences. LÄS MER
