Conclusion and future perspectives
The lithic assemblage from Scord of Brouster adds valuable elements to the discussion of regionality in the Scottish Neolithic period. By comparing this collection with contemporary material from other regions of Scotland, it has been possible to define two distinctly different raw material provinces, as well as a third hybrid form. The quartz province, to the north and west, and the flint/chert province, covering the eastern, central and southern parts of the country, have been characterised as techno-complexes. A techno-complex is composed of a number of social territories between which there is usually a low degree of social interaction.
