  1. 1. Post-IR IRSL dating of K-feldspar from Loess at Lowland Point, SW England : Developing a Chronology for Past Climate Records

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elin Törnqvist; [2022]
    Keywords : loess; post-IR IRSL; Lowland Point; SW England; Quaternary; löss; post-IR IRSL; Lowland Point; England; kvartär;

    Abstract : Loess deposits are terrestrial clastic sediments derived from aeolian deposition. Loess is transported in periglacial conditions and was mainly deposited in cold environments around glaciers during the Quaternary period. READ MORE

  3. 2. High Sampling Resolution Luminescence Dating of Loess in Brittany, France

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Vanda Jakabová; [2021]
    Keywords : aeolian dust; loess; luminescence; dMAR; Brittany; LGM; palaeoenvironment; eoliskt damm; loess flygmo ; luminescens; dMAR; Bretagne; LGM; paleomiljö;

    Abstract : Aeolian dust is an important but poorly understood component of the climate system, which both responds to and drives global climate. Recently, dust produced at the high latitudes is also gaining attention as a possible contributor to the atmospheric dust load. READ MORE

  4. 3. Dustiness Testing and Particle Characterization of CNT-enhanced Concretes

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Sara Marsh; [2021]
    Keywords : concrete; dustiness; airborne particles; carbon nanotubes; Technology and Engineering;

    Abstract : The introduction of fibers into concrete is a common way of reinforcing the mechanical properties and preventing cracking. The fibers act as bridges between the composite components and help reduce the porosity. Today, micrometer-sized fibers are widely used, but there is an increased interest in using smaller fibers e.g. READ MORE

  5. 4. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Pelle Kronborg; [2020]
    Keywords : loess; XRF; weathering index; England; Lowland Point; Porth Cressa; Quaternary; löss; XRF; vittrings index; kvartär; England; Lowland Point; Porth Cressa;

    Abstract : 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. READ MORE

  6. 5. Aeolian and Pedogenic Processes of Loess in Southern England

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ragna Orbe; [2019]
    Keywords : loess; Pegwell Bay; grain size distribution; magnetic susceptibility; past-climate reconstruction; lössavlagringar; Pegwell Bay; partikelstorleks distribution; magnetisk mottaglighet; historisk klimatrekonstruktion;

    Abstract : 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.
