  1. 1. Seismic investigations and physical property studies of natural resources in Finland and Sweden : Efficient exploration of groundwater and mineral resources

    Författare :Georgiana Maries; Alireza Malehmir; Christopher Juhlin; Musa Manzi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; seismic refraction; esker; glacial sediments; iron-oxide; hardrock; efficient exploration; physical property; forward modeling; seismic quality factor; Finland; Sweden; Bergslagen;

    Sammanfattning : Natural resources, such as mineral deposits and groundwater in particular, are crucial for our society, as the world prepares itself for a smooth transition towards green technologies and decarbonization. Apart from extraction and use, innovative mineral exploration solutions are needed to complete the full value chain and to achieve the sustainable development goals. LÄS MER

  3. 2. Lithology of some Swedish eskers

    Författare :Marianne Lilliesköld; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Three esker systems passing different bedrock areas are lithologically investigated. Mostparts of the eskers are of subglacial, subaquatic type. The existence of a preglacial furrowof the River Dalälven is proposed to be the cause of the longtransported lithologiesfound in the Badelunda esker adjacent to the furrow. LÄS MER

  4. 3. Integrated geophysical-geochemical methods for archaeological prospecting

    Författare :Kjell Persson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; geophysical; geochemical; prospecting; archaeology; electric; magnetometric; Geofysik; Geophysics; Geofysik;

    Sammanfattning : A great number of field measurements with different methods and instruments were conducted in attempts to develop a method for an optimal combination of various geochemical and geophysical methods in archaeological prospecting. The research presented in this thesis focuses on a study of how different anthropogenic changes in the ground can be detected by geochemical and geophysical mapping and how the results can be presented.

    Sammanfattning : The remains of a wooden stronghold and a fortified manor have been found in Hedemora and Husby parishes in southern Dalecarlia, along with a late medieval city and the northernmost monastery in Sweden. They all stem from the period between about 1350 and 1500. LÄS MER

  7. 5. Application of some statistical methods for evaluation of groundwater observations

    Författare :Björn Ackerberg; KTH; []
    Nyckelord :;

    Sammanfattning : With the objective of reviewing different statisticalmethods for evaluation of groundwater data and the design of agroundwater observation network, a comprehensive literaturesurvey was performed. The literature survey focuses on spatialstatistics (geostatistics) but also includes methods toevaluate time-series of groundwater data and the determinationof the sampling frequency. LÄS MER
