The petrology of stone axes found in the Channel Islands is examined. Recent research has resulted in the identification of an axe production center at Le Pinacle, Jersey, and axes produced there have been recorded on Guernsey, Alderney, and Sark. The Channel Island assemblages also include axes of Type A dolerite, flint, jadeite, eclogite, and fibrolite, produced at known centers on the European mainland; together, these exotic axes account for around 32% of the total Channel Island sample. A marked fall-off is noted between Jersey and the other islands in terms of the occurrence of these imported axes, and this can perhaps be explained in relation to factors affecting navigation. The social significance of interisland and island/mainland interaction is explored.
