  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

  2. 2. Combining luminescence dating and sedimentary analysis to derive the landscape dynamics of the Velická Valley in the High Tatra Mountains, Slovakia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Roos van Wees; [2020]
    Keywords : IRSL; Chronology; Sedimentology; Landscape development; Middle Pleistocene; Modern Analogues; Clast shape analysis; Maximum particle size; High Tatras; Slovakia; Earth and Environmental Sciences;

    Abstract : Luminescence dating is widely used in combination with sedimentological analysis to reconstruct the landscape development of the Quaternary period. Here, quartz and K-feldspar measurements are used to date and evaluate the luminescence characteristics of sediments from seven sites of the lower part of the Velická valley (995-1250 m a.s.l.

  3. 3. Using Bulk XRF-Analysis of Chinese Loess to Determine High-Resolution Records of Dust Provenance

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexandra Engström Johansson; [2017]
    Keywords : dust; provenance; elemental ratios; Chinese Loess Plateau;

    Abstract : Understanding the sources of the dust that forms the extensive loess deposits on the Chinese Loess Plateau is crucial for reconstructing atmospheric circulation patterns and dust pathways. Dust sources are however highly debated, mainly due to the low resolution of many records and the often ambiguous nature of geochemical proxies. READ MORE
