1. The Biogeographical Extent and Global Synchronicity of the Late Miocene Reticulofenestra pseudoumbilicus Paracme
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Previous biostratigraphic studies in the Indian Ocean, equatorial Pacific, Atlantic Ocean and the Caribbean Sea document the temporal disappearance of Reticulofenestra pseudoumbilicus in the late Miocene (Tortonian age). This interval has been subsequently defined as the R. pseudoumbilicus paracme. LÄS MER
2. Relating early Human evolution to late Miocene - early Pliocene climate change
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Human evolution has been linked to climate change multiple times in the literature. One of the more well-known theories is the ‘savannah’ theory, which states that walking upright became an advantageous character when climate in Africa changed causing drier environments, changing woodlands to savannahs.

3. The Neurocranium of Anasinopa leakeyi (Hyaenodonta, Mammalia) – a First Insight into Teratodontine Brain Morphology
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Hyaenodonta include a wide variety of carnivorous mammals ranging in age from late Palaeocene to middle Miocene. Although they reached a nearly global distribution, little remains of them today. Many of the taxa are based only on teeth and jaw fragments. LÄS MER
4. Investigation into the Loess-Palaeosol and Red Clay Record from the Pliocene- Quaternary Chinese Loess Plateau Using In-Phase and Out-OfPhase Magnetic Susceptibility
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Loess is a well sorted, fine grained, windblown (aeolian) sediment and deposits as a blanket over large areas, reaching from a few centimetres to several hundreds of meters in height and can drape large landscapes in form of mountains. During a more humid and warmer climate, redox conditions are changed in the loess deposits, with greater seasonal moisture creating greater soil formation (pedogenesis), i. LÄS MER
5. An Analysis and Interpretation of the Geoscience BC Trek Project Till Geochemical and Mineralogical Data to Determine the Surficial Geochemical Expression of Bedrock Au-Ag-Cu-Mo Mineralization on the Nechako Plateau, British Columbia, Canada.
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The mineral exploration in the interior of British Columbia is challenged by an extensive coverage of glacial sediments. The Geoscience British Columbia (GBC) Targeting Resources through Exploration and Knowledge (TREK) Survey has since 2013 collected till samples in the northern interior plateau of British Columbia, covering an area of approximately 25,000km2.
