26. Temporal evolution of historic mafic lavas from Fogo, Cape Verde
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The volcanic Island of Fogo that is situated near the end of the southern island chain in the archipelago of Cape Verde is one of the most active oceanic volcanoes in the world. The purpose of this study was to investigate temporal variations in lavas from Fogo by using whole rock major and trace elements and describe trends in magmatic differentiation, melting systematics and mantle source compositions.

27. U-Pb geochronology and geochemistry of host rocks to the Bastnäs-type REE mineralization in the Riddarhyttan area, west central Bergslagen, Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The geochronology of felsic metavolcanic rocks hosting the Bastnäs-type rare earth element (REE) mineralization in the Riddarhyttan area in the Bergslagen region, Sweden, was investigated using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) U-Th-Pb on zircon and monazite. U-Pb data from four host rock samples yield dates of 1899 ± 4 Ma (MSWD=2. LÄS MER
28. Heterogen katalys för produktion av biodiesel från rester av matolja
Kandidat-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : Energikonsumtionen inom transportsektor består till störst del av konsumtion av fossila bränslen. Transportsektorn själv står för ca 30 % av världens totala energikonsumtion. Att växla till ett grönt drivmedel skulle bidra till en mer ekologiskt hållbar verksamhet. LÄS MER

30. Alteration of the Bjursås Ore Field, Oxberg, Bergslagen District, Sweden
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Bjursås ore field is located within the Bergslagen domain of central Sweden just northwest of the town of Falun. The field hosts small scale mines such as the 17th century Floberg copper mine and has been the focus of mineral exploration on several occasions during the 20th and early 21th century, with no major economic deposits being uncovered as of yet.
