  1. 1. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Per Wahlquist; [2023]
    Keywords : volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

    Abstract : 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.

  3. 2. Reconstructing Past Climate by Grain Size and Magnetic Susceptibility Analysis of Belgium Loess From the Late Quaternary

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Susanna Åberg; [2022]
    Keywords : aeolian dust; Romont; Europe; true loess line; past climate reconstruction; vindtransporterat stoft; Romont; Europa; true loess line; rekonstruktion av tidigare klimat;

    Abstract : Aeolian dust that gets deposited builds up loess sequences that cover 10% of the Earth's continents. Such sequences can be several metres thick with material deposited over thousands of years, and therefore act like archives of past climates. READ MORE

  4. 3. Reconstruction of paleoclimate and loess provenance during the last glacial in Jersey using XRF analysis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Matilda Persson; [2022]
    Keywords : loess; origin; La Motte; XRF; Quaternary; weathering; climate; lössjord; ursprung; La Motte; XRF; kvartär; vittring; klimat;

    Abstract : 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. READ MORE

  5. 4. Oolites from the Arabian platform: Archives for the aftermath of the end-Triassic mass extinction

    University essay from Lunds universitet/Geologiska institutionen

    Author : Johannes Greiff; [2021]
    Keywords : sedimentology; carbonates; geochemistry; oolites; ooids; thrombolites; microbialites; Triassic; Jurassic; Hettangian; extinction; United Arab Emirates; Wadi Ghalilah; Wadi Milaha; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  6. 5. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Andersson; [2021]
    Keywords : geochemistry; loess; XRF; weathering; climate change; N-W France;

    Abstract : 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. READ MORE
