  1. 1. Stratigraphic and palaeoenvironmental observations in the deposits of a postglacial kettle hole, in the county of Västernorrland

    University essay from Umeå universitet/Institutionen för idé- och samhällsstudier

    Author : Genofeva Eva Kourela; [2020]
    Keywords : Multiproxy analysis; palaeoenvironment; minerals; peat accumulation; kettle hole; Coleoptera; environmental archaeology;

    Abstract : The increased human impact on the environment and climate after the retreat of the Last Glacial has strengthened its importance in the region of Västernorrland where Mesolithic sites are evident. This study focuses on a multiproxy analysis, where archaeological and natural science methods are combined to test several techniques in a peat sample. READ MORE

  3. 2. Evidence for birch forests and a highly productive environment near the margin of the Fennoscandian ice sheet in the Värriötunturit area, northeastern Finland

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Fredrik Bogren; [2019]
    Keywords : Early Holocene; productive ice-marginal environment; subarctic birch forests; plant macrofossils; pollen; palaeoenvironmental reconstructions; palaeoclimate reconstructions; Värriötunturit; Kuutsjärvi; northeastern Finland; northern Fennoscandia;

    Abstract : High-resolution records of early Holocene deposits are rare, and as a consequence reconstruction of terrestrial environments very soon after the deglaciation has often been difficult. In this study the palaeoenvironmental conditions of early Holocene (c. 10600-7500 cal. READ MORE

  4. 3. Different generation of controlled moraines in the glacier foreland of Midtdalsbreen, Norway

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Xavier Allègre; [2018]
    Keywords : Glacial sedimentology; glaciology; geomorphology; palaeoenvironmental reconstruction;

    Abstract : A series of small mounds (< 3m) were sampled in the foreland of Midtdalsbreen outlet glacier, southern Norway. These landforms were interesting, especially at site number 1 because they were located very close to a higher Little Ice Age (LIA) moraine (> 5 m), thereby informing the dynamic of the glacier after the LIA at this location.

  5. 4. Palaeoenvironmental reconstruction of catchment processes in sediments from Bolgoda Lake, Sri Lanka

    University essay from Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Filosofiska fakulteten

    Author : Frida Eriksson; Daniel Olsson; [2015]

    Abstract : Bottom sediment is an archive of the historical changes in a lake and its catchment. This thesis is apalaeoenvironmental reconstruction of catchment processes in Bolgoda Lake situated in western SriLanka. We studied a sediment core retrieved from this lake. READ MORE

  6. 5. Late Holocene palaeoenvironmental reconstruction on a peat sequence from northeastern South Africa, using grass phytoliths as main proxy

    University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Jenny Sjöström; [2013]
    Keywords : Late Holocene; South Africa; Palaeoenvironmental reconstruction; Phytolith; Bokoni;

    Abstract : Contemporary a geographical imbalance of where palaeoclimatological studies have been undertaken exists, where the majority of palaeodata is based on studies from the northernhemisphere. Multiproxy analysis was performed on a peat core from Lydenburg, north-eastern Mpumalanga, covering the last 1.600 years. READ MORE
