1. Magmatic processes and storage beneath Heard Island, southern Indian Ocean
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : A young marine island called Heard Island is located in the southern Kerguelen Plateau in the Indian Ocean, a large igneous province created by the Kerguelen mantle plume. The two major geographic regions on Heard Island have two principal volcano-magmatic suites. LÄS MER
2. Studying magmatic systems through chemical analyses on clinopyroxene - a look into the history of the Teno ankaramites, Tenerife
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Clinopyroxenes have the ability to crystallize over and respond to a large range of temperatures, pressures and chemical compositions, and thus, they are ideal for studies regarding the history of magmatic systems. In this thesis, the chemistry and zoning of four clinopyroxene crystals from an ankaramite sample from the Teno massif, Tenerife, were analysed. LÄS MER
3. Major and trace element geochemical analysis of norites in the Hakefjorden Complex to constrain magma source and magma plumbing systems
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Major and trace element data taken from plagioclase crystals from anorthosites and related rock units in the Hakefjorden Complex located off the west coast of Sweden were investigated for the purposes of constraining magma chamber processes and the source of the magma. Although the anorthosite units were completely homogenous in regards to its chemistry, the plagioclase in the associated norite and ilmenite-leuconorite units showed substantial variation. LÄS MER
4. Magma Evolution of the Cerro Bayo Laccolith in the Chachahuén Volcanic Complex, Argentina
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Chachahuén volcanic complex, with the Cerro Bayo laccolith as one of the largest intrusions, is part of back-arc Payenia volcanic province in western central Argentina. Laccoliths show potential for generating oil in sedimentary basins and producing ore deposits. LÄS MER
5. Magmatic Sources and Processes Recorded by the Volcanics from the Izu Bonin Rear Arc
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Izu rear-arc volcanism was investigated by IODP EXP350 in spring 2014. A total stratigraphy of1800 m was drilled, and contains volcaniclastic material within tuffaceous mudstone. LÄS MER
