Report on use-wear analysis of tools of quartz and other raw materials from two sites in Torsåker parish, Gästrikland
The two analyzed samples come from two Mesolithic costal sites situated in southern part of Norrland. 25 quartz artefacts from the site of Flyttblocket and 53 quartz artefacts from the site of Hästboberget were selected for analysis. In all, 14 different types of raw material were classified in the sample. The quartz artefacts were classified according to fracture pattern classification used in Scandinavia in order to define the real prehistoric tool use and production. A fragmentation scheme is also presented in the report. The slightly later of the sites, Flyttblocket was very small as to area and recovered remains. The analyzed material is very homogenous as to raw material. Production methods and use-wear analysis point to an interpretation of this place as a stone tool production site, rather than a place where people stayed and lived for longer periods of time. However, 25-30% of the analyzed items show traces of wear. This means that people retooled their old tools or performed other tasks on the site rather than only knapping. The second site, Hästbobeget, was much larger in extent and material. Raw material variation was substantial. Use-wear and technology analysis allow for an interpretation of the site as a living and working area. Previously not registered tool types have been found in the material. Illustrations to this reasoning are stored in the analysis report in Swedish.
