1. Rituelle og hverdagslige hester: En komparativ stabil isotop studie av hestene fra våtmarken Bokaren og Gamla Uppsala
Master-uppsats, Stockholms universitet/Institutionen för arkeologi och antikens kulturSammanfattning : The aim of this thesis is to expand the understanding of horses from ritual and everyday contexts, respectively, by investigating their diet and mobility. In this thesis, teeth of domestic horse Equus ferus caballus from the wetland Bokaren and central place Gamla Uppsala in Uppland during the late Iron Age (550-1050 A.D) are analyzed. LÄS MER
2. Major and trace element geochemical analysis of norites in the Hakefjorden Complex to constrain magma source and magma plumbing systems
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Major and trace element data taken from plagioclase crystals from anorthosites and related rock units in the Hakefjorden Complex located off the west coast of Sweden were investigated for the purposes of constraining magma chamber processes and the source of the magma. Although the anorthosite units were completely homogenous in regards to its chemistry, the plagioclase in the associated norite and ilmenite-leuconorite units showed substantial variation. LÄS MER
3. The Victims at Sandby Borg : Tracing mobility and diet usingstrontium analyses
Master-uppsats, Stockholms universitet/Arkeologiska forskningslaboratorietSammanfattning : Sandby borg, an Iron Age ringfort on Öland, Sweden has been and is still at the center of attention in media and archaeological research. The massacre uncovered at the site during recent years opens many doors for analyses on the Migration Period (c. 400-550 AD) Iron Age skeletal remains. LÄS MER
4. Lokale eller ikke-lokale grønlandsseler fra Asva, Estland, under eldre bronsealder
Kandidat-uppsats, Stockholms universitet/Arkeologiska forskningslaboratorietSammanfattning : This thesis deal with three individual Pagophilus groenlandicus canin teeth from the location Asva, Estonia dating from the Late Bronze Age (here 700-900 B.C). The aim of this thesis is to find out whether the three harp seal individual was local or non-local to Asva and further if they were migrants from the Atlantic Sea. LÄS MER
5. Rb-Sr sphalerite data and implications for the source and timing of Pb-Zn deposits at the Caledonian margin in Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The eastern Caledonian erosional front hosts the world-class Pb-Zn deposit at Laisvall (64 Mt mined) and Granberget mineralization, northern Sweden, along with several other smaller, related types of deposits consisting of impregnation mineralization of galena and sphalerite in clastic host rocks. Previous work have discussed the nature of the ore-forming processes and constraints for the timing of the mineralization, however, the mechanisms are still not fully understood and previous age determinations are ambiguous.
