axe roughout (drawing) |

Description |
English: Greenstone or metadolerite axe roughout, which has been petrologically analysed by Dr. Roger Taylor as part of the Clodgy Moor Project. The roughout is a bladed cobble that is ovate in plan and section, and lozenge-shaped in profile. There are more invasive flake scars at the butt end of the roughout, and on the left margin of the ventral face, and there is a concentric crack that carries on around the dorsal face of the roughout, curving inside the blade end. This suggests that the roughout has been trimmed by splitting as well as chipping, and then smoothing. Similar examples are turning up from the same area of the moor which suggests a possible local source or outcrop for this rock type. The greenstone is typical of that found in the west of Cornwall from known outcrops, and contains pale felspar and dark amphibole inclusions (Dr. Roger Taylor pers comm - see notes below).
Examples of similar roughouts and axes have been excavated from the Neolithic settlement at Carn Brea (Mercer, 1981) and are referred to and illustrated on pages 155 & 158, Fig.64, Nos.S7 & CO166. |
