The discovery of a Neolithic quarry and production site for basanite bifacial tools at Giv‘at Kipod in Israel has provided new insights into these socially significant artefacts. Geochemical analysis of material from the quarry distinguishes it from other basaltic rock sources in Israel, allowing stone tools from a variety of sites and dated contexts to be assigned a provenance. Results suggest that Giv‘at Kipod was an important production centre for over several millennia. It operated primarily on a local, regional level and independently of the parallel manufacture-and-distribution mechanisms of flint bifacials. While flint tools developed in response to the practical requirements of the transition to agriculture in the region, ground-stone bifacials appear to have been a product of economic changes and evolving social structures.

The authors describe the discovery of a Late Neolithic/Chalcolithic basalt axe factory in the Manasseh Hills in Israel and suggest it had a primary role in the region for the production of these functional and symbolic tools. The form of discarded roughouts and flakes is used to deduce the principal eventual product and its sequence of manufacture.
