  1. 6. Influence of Sample Preparation on Portable XRF-analyses of Aeolian Sediments: a Case Study

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Markus L. Fiola; [2017]
    Keywords : portable XRF; loess; sediment; bärbar XRF; lössjord; sediment;

    Abstract : The geochemical composition of aeolian sediments like windblown dust particles is of major importance for the exploration of dust origin and weathering conditions. This allows for the reconstruction of dust transport pathways and thus wind directions and palaeoclimate conditions. READ MORE

  3. 7. Identification and environmental interpretation of microtextures on quartz grains from aeolian sediments : Brattforsheden and Vittskövle, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Marijana Stevic; [2015]
    Keywords : microtextures; quartz grains; aeolian sediments; occurrence; environmental interpretation; scanning electron microscope; Earth and Environmental Sciences;

    Abstract : Mikrotexturer är mikrometerstora avtryck på kvartskornens ytor samt på korn med andra mineralogiska egenskaper. Kvartskorn, som förekommer i de flesta sedimentära miljöer, innehåller mikrotexturer som undersöks särskilt på grund av kvartsmineralets unika mineralogiska egenskaper som möjliggör bevarandet av mikrotexturer genom olika miljöer.

  4. 8. Distribution and Mobility of Arsenic in the Shallow Aquifers of Northeastern of La Pampa Province, Argentine.

    University essay from KTH/Mark- och vattenteknik

    Author : Anna Aullón; [2013]
    Keywords : Arsenic; fluoride; shallow aquifer; La Pampa; loess sediments and volcanic ash;

    Abstract : More than two million people in the Chaco-Pampean plain in central Argentina are affected by high As levels in groundwater. The concentrations of As are far exceeding the WHO standard limit for safe drinking water of 0.1 μg/L and the provisional Argentinean limit of 0.5 μg/L. READ MORE

  5. 9. Optically Stimulated Luminescence (OSL) dating of aeolian sediments of Skåne, south Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Rajendra Shrestha; [2013]
    Keywords : Vomb basin; South Sweden; Skåne; Aeolian; Sediments; Grain size; Luminescence; OSL; Chronology; Earth and Environmental Sciences;

    Abstract : Wind is an important agent of transportation of sediments and to change the landscape. Aeolian sediments can be inferred as a proxy for past climate. In Sweden aeolian sediments are not widespread and there are not so many studies on chronological and paleoenvironmental aspects. READ MORE
