Abstract. The goal of this case study is to further the understanding of the social and economic structure, such as trade routes and/or prehistoric man’s movement, during prehistory in the inland of Västerbotten, Sweden. This is achieved by studying the sets of lithic tools found in six archaeological sites (RAÄ 977:1 Vilhelmina, RAÄ 553:1 Vilhelmina, RAÄ 132:1 Vilhelmina, RAÄ 519:1 Vilhelmina, RAÄ 399:1 Vilhelmina och RAÄ 129:1 Åsele) using NIR-spectroscopic (Near InfraRed-spectroscopy), statistical and archaeological methods. By using PCA-models (Principal Component Analysis-models) and the classification method SIMCA (Soft Independent Modelling of Class Analogies) on NIR-spectroscopic data collected over the course of this study, it was possible to show signs that prehistoric man in the studied area, might have deposited quartzite materials, not naturally occurring at the RAÄ 519:1 Vilhelmina, Sweden, site. Four geographic areas (the vicinity of the sea Vojm, the North and South part of the sea Malgomaj and the vicinity of the Southwest part of the Ångerman river in the studied area) could also be shown to display distinct patterns in the PCA-models, related to the use of particular combinations of quartzites. These findings lead to the conclusion that prehistoric man in this area, typically used locally available materials for toolmaking. Furthermore, this study resulted in a large NIR-spectroscopic dataset from the archaeological sites that makes up the main material for this study, that may be beneficial to future NIR-spectroscopic studies in archaeology and/or further studies of NIR-spectroscopy applied to lithic materials.
