  1. 16. Isotopic studies of two early Proterozoic sulphide ores in the Bergslagen district, south-central Sweden

    Författare :Kjell Billström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Two sulphide ores in Beraslaqen (Svärdsio and Ammeberq), south-central Sweden, have been examined for their isotope characteristics in order to elucidate their qenetic oriqin. The obtained isotopic data point to a common volcanic-exhalative mode of formation in aqreement with recent qeochemical data. LÄS MER

    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Stone Age; Early Neolithic; Funnel Beaker Culture; Funnel Beaker pottery; polygonal batte-axes; farmers; hunter-gatherers; culture; practice; identity; communities of practice; Archaeology; Arkeologi;

    Sammanfattning : This thesis discusses the introduction of cultural practices such as cultivation, cattle herding, pottery craft and specific lithic traditions in the region around the Baltic Sea during the Stone Age. The main focus is on the Early Neolithic (4000-3300 cal. BC) Funnel Beaker Culture of Mälardalen and Bergslagen in eastern Central Sweden. LÄS MER
