    Revisiting Key Sedimentary Archives Yields Evidence Of A Rapid Onset Of Mining In The Mid-13th Century At The Great Copper Mountain, Falun, Sweden2016Ingår i: Archaeometry, ISSN 0003-813X, E-ISSN 1475-4754, Vol. 58, nr 4, s. 642-658Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Mining in Falun, Sweden, was first mentioned in a deed from AD 1288, but previous studies of peat and lake sediments inferred that mining began during the fifth to eighth centuries. In order to reassess these findings, we performed new geochemical analyses on new samples from three key sites: Tisksjobergets myr, a buried mire alongside the mine; Tisken, a small lake in Falun; and Runn, the main recipient for waters draining through Falun. At Tisksjobergets myr, the peat contains up to 6% copper, giving it the characteristics of a cupriferous bog. Hence, this record is not useful for tracing early mining. The sediments of Tisken-upon which many of the old interpretations have relied-contain numerous cut wood fragments, and two of those gave young and reversed radiocarbon dates (19th and 16th centuries for 192 and 187 cm, respectively). This indicates that the sediment was derived from infilling and, thus, has little value as a historical record. Runn's sediment-the only reliable record-provides clear evidence of a rapid onset of large-scale mining from c. AD 1245, with abrupt increases in ore-related elements-for example, a 34-fold increase in copper-this increase is consistent with the mid-13th century burial of the mire at Tisksjoberget.

    When a Waterhole is Full of Dung: An Illustration of the Importance of Environmental Evidence for Refining Archaeological Interpretation of Excavated Features2019Ingår i: Archaeometry, ISSN 0003-813X, E-ISSN 1475-4754, Vol. 61, nr 4, s. 977-990Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Prehistoric field systems sometimes encompass excavated, pit-like features which are difficult to classify due to the complex stratigraphies resulting from reuse, infilling and collapse. They are frequently classified as wells and watering holes, but other potential uses for excavated depressions are rarely cited. We argue the need for environmental archaeology in the interpretation of features of this nature, and present a case study from a Bronze Age site at Pode Hole, near Peterborough (UK), where fossil insect material clearly contradicts the archaeological interpretation. We present empirical evidence for a sealed context filled with dung which cannot be interpreted as a water source. This evidence strongly contrasts with other superficially similar features at the site.

    Provenancing flint artefacts with ICP-MS using ree signatures and Pb isotopes as discriminants: preliminary results of a case study from northern sweden2011Ingår i: Archaeometry, ISSN 0003-813X, E-ISSN 1475-4754, Vol. 53, s. 1142-1170Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Archaeological flint artefacts from the late Mesolithic/early Neolithic site of Vuollerim, northern Sweden, have been geochemically investigated with ICP-SFMS and MC-ICP-MS in search for the geological/geographical origin of the non-local flint. The Vuollerim flints were compared with reference samples from Denmark (Cretaceous/Tertiary flint) and Russia (Carboniferous flint). Elemental concentrations as well as elemental ratios for REEs and isotopic ratios for Pb and Sr are presented. Significant differences were found between different geological/geographical contexts. Two of the Vuollerim samples can be ascribed a South Scandinavian origin. Possibly also eastern flint is present, although the results are not conclusive in this case.
