The flint mine of Ri «Le Fresne»

Abstract

The flint mine of Ri is located at +200 to +205m NGF (Nivellement Général de la France) on a southeastward slope, in the north of the Houay’s Valley, whose eponym river is a tributary of the Orne. The raw material mined at this site has the shape of spherical mid-grain-sized pebbles, measuring 20cm in diameter and 50cm in length. They outcrop in a powdery limestone layer, 1.2m in depth at the southern end of the excavated area to 4.5m at the northern end. From shallow to deep areas, the infrastructure of the mine varies from incurved holes to 30 square meters pits radiating a network of small galleries and extensions. While some of these galleries remained unfi lled, most pits were refi lled immediately after the extraction of fl int. Their walls contain a great number of digging tool traces. Twenty eight radiocarbon dates have been obtained on deer antlers recovered from the entire surface of the excavation, situating the mine in the second half of the fourth millennium BC.
