6. Oolites from the Arabian platform: Archives for the aftermath of the end-Triassic mass extinction
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The end-Triassic mass extinction (ETME) which occurred around 201 Ma is known as one of “the big five” mass extinction events of the Phanerozoic eon. Its effects were most severe on marine ecosystems, resulting in a global decline of invertebrate taxa and the complete extinction of the conodonts. LÄS MER
7. Kan Skåne uppnå en cirkulär förvaltning av näringsämnen - En systemanalys över mat- och restströmssystemet i Skåne
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : Nitrogen, phosphorus, and potassium are essential for the survival of humans, animals, and plants. The production and usage of mineral fertilizer has contributed to an over-use of these resources, leakage, and emissions of nutrients. This study aims to simplify and simulate the food system of Scania through a conceptual model. LÄS MER
8. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. LÄS MER
9. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. LÄS MER
10. Arctic Loess as an Environmental Archive : Identifying Weathering with XRF Analysis in West Greenland
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Loess from west Greenland was studied to evaluate Holocene paleoclimate in the Arctic region. Deposits of loess are formed over long time scales through deposition of fine aeolian sediment and they exist in several places in the world. LÄS MER
