Fieldwork by the Dyfed Archaeological Trust during 1989–92 has identified clear evidence for the manufacture of stone axeheads at two locations on the eastern flanks of the Preseli Mountains, Dyfed: at Glyn-y-Fran, Llanfyrnach (SN 186 307) and near Glandy Cross (SN 143 266). At both sites, small quantities of lithic debris were collected from field surfaces after cultivation; unfortunately, no contemporaneous features were found by subsequent, very limited, trial trenching. In this report we describe the fieldwork at these two sites, and the resulting lithic collection, concluding that the latter represents evidence for small-scale and opportunistic exploitation of locally abundant erratics during the Neolithic. The Glandy Cross area was later a focus for the construction of ritual monuments during the Bronze Age, and there is also some evidence for continuing activity at Glyn-y-Fran at this time.Petrological thin section analysis of some of the artefacts is reported and demonstrates a probable identity with petrological Group VIII; geochemical analysis of some of the same artefacts places the likely geological origin of these at local igneous exposures also in the Preselis. These conclusions are reviewed in the light of current discussion on the usage and origins of raw materials in later prehistory.
