Kulturkontakter i Sydskandinavien under mesolitikum : Hantverkstraditioner, råmaterialval och mobilitet för 9000 år sedan, med utgångspunkt från Norje Sunnansund i Blekinge

The purpose of this thesis is to investigate different scales of mobility and social networks in Southern Scandinavia around 7000 BC. An essential basis for this work is the hypothesis that the conical core pressure blade technology, a specific method for producing lithic blades, reached Scandinavia from the east. The process has been discussed and verified in several earlier studies. The study is based on investigations of lithic material and bone tools, as well as human skeletal remains; a multidisciplinary strategy has been applied, which combines technological analyzes of archaeological material with isotope analyzes of human teeth. Materials and data have been collected from a total of 111 sites located mainly in Scandinavia, but also in Finland, the Baltic countries and Russia. The Mesolithic site Norje Sunnansund in Blekinge, southern Sweden is in focus. Analyzes of the chaîne opératoire of lithic and osseous production make it possible to study technological processes as the transmission of culturally conditioned patterns; these patterns underlie the formative principles of each technology complex. By identifying specific traditional knowledge built into the material process, it becomes possible to define prehistoric human traditions and thereby study human interactions and migrations between geographical regions. The analyzes of strontium isotopes in human teeth from Norje Sunnansund enables an additional individual provenancing since the isotopes reflect a geographical-geological variation. The study provides a higher resolution of the arrival and spreading of the pressure blade technology from the northeast. It also strengthens the picture of a Mesolithic society in Southern Scandinavia based on geographically extensive social networks. An increased regionalization and territorialization has previously been proposed for western Scandinavia around 8800-7500 BC. The study confirms that during this period the population seem to consist of several subgroups related to specific territories, but with close and regular contact within a more extensive social network. This fits well with the picture of a group that may have inhabited Norje Sunnansund for extended periods, while social contacts were maintained over longer distances
