  1. 1. 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

  3. 2. Late Quaternary Climate Reconstruction Using Rock - Magnetism in Loess on Portelet, Jersey
