    Författare :Andreas Viberg; Kerstin Lidén; Bo Olofsson; Rinita Dalan; Bruce Bevan; Neil Price; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeological prospection; geophysical survey; Sweden; Ground-penetrating radar; magnetometry; Slingram; magnetic susceptibility; Neolithic; Migration period; Viking Age; Middle Ages; Öland; Gotland; Sigtuna; Lapland; Archaeological Science; laborativ arkeologi;

    Sammanfattning : The aim of this thesis has been to investigate the benefits, pitfalls and possibilities of using geophysical methods in archaeological projects. This is exemplified by surveys carried out at archaeological sites in different geographical and chronological contexts. LÄS MER

  3. 2. 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 aim of this thesis has been to investigate and interpret late Iron Ageand Early Medieval traces of non-ferrous metalworking on the islandGotland, Sweden. Gotland was not, based on the archaeological record, anintegrated part of the common Scandinavian culture. LÄS MER

  7. 5. Geophysical studies of the upper crust of the central Swedish Caledonides in relation to the COSC scientific drilling project

    Författare :Peter Hedin; Christopher Juhlin; Alireza Malehmir; Bjarne Almqvist; Charles Hurich; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reflection seismic; collisional orogeny; Scandinavian Caledonides; COSC; scientific drilling; geophysical logging; gravity; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The Collisional Orogeny in the Scandinavian Caledonides (COSC) project aims to provide a deeper understanding of mountain belt dynamics through scientific deep drilling in the central parts of the mountain belt of western Sweden. The main targets include a subduction related allochthon, the basal orogenic detachment and the underlying partially subducted Precambrian basement. LÄS MER
