1. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

2. Reconstruction of paleoclimate and loess provenance during the last glacial in Jersey using XRF analysis
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : With our changing climate it becomes more vital to understand the processes that control climate change in order to better understand possible future shifts. By doing this, predictions can be made about future climates and better prepare us for them. LÄS MER
3. 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
4. Aeolian and Pedogenic Processes of Loess in Southern England
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Loess is an aeolian sediment that can be utilized as a detailed proxy of past climate, since it is one of few sediments that is deposited directly from the atmosphere on land. Investigation of loess deposits can give understanding of past regional and local wind circulation patterns and velocities, atmospheric dustiness, as well as paleo-precipitation and weathering conditions.

5. Sedimentological study of the Jurassic and Cretaceous sequence in the Revinge-1 core, Scania
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : This thesis presents a study of the core from the Revinge-1 borehole from the Vomb Trough. The core displays strata from the Upper Jurassic to the Upper Cretaceous including strata covering the the J/K−boundary . LÄS MER
