  4. 3. Towards a Holocene tephrochronology for the Azores

    Författare :Hans Johansson; Stefan Wastegård; Otto Hermelin; Ewa M. Lind; Christine S. Lane; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kvartärgeologi; Quaternary Geology;

    Sammanfattning : The Azores is situated in the North Atlantic Ocean and is one of the most active volcanicregions in the Northern Hemisphere. The volcanic history of the islands is fairly wellknown and several explosive trachytic eruptions have been reported but the geochemicalcompositions of the glass component of the tephra as well as the dispersal oftephras to distal areas are less well known.
