These characteristics indicate an origin from fl int lamination. An attribution of these artefacts to the group of eluvia, that is places where fl int slabs outcrop due to Valkenburg fl int is less certain. We could also be dealing here mechanical weathering and dissolving of the top of the chalk. with a variation of Simpelveld fl int in which the layering, as Slope deposits also qualify as raw material source. On the visible in the patina, is less pronounced than in artefacts that narrow sides of the fl int slabs, natural, blunt break surfaces have been described as Simpelveld fl int. The fact that there can be present in places where the cortex is absent.
