Quartzite complexities: Non-destructive analysis of bifacial points from Västerbotten, Sweden

•Non-destructive analysis of prehistoric quartzite bifacial points.•Near-infrared spectroscopy, Raman scattering and X-Ray Fluorescence.•Each method detects differences in structural and chemical characteristics.•Individually, resolution is too low for classification of this material.•Data fusion techniques are recommended for future modelling.
