In the “Sierra de Araico - Montes de Cucho” (Treviño, Burgos and Berantevilla, Álava), in the South-Pyrenean of Miran- da-Treviño (Basque-Cantabrian Basin), materials from the continental Tertiary of the Miocene (Aquitaine) outcrop. It is a set of lacustrine-palustrine limestones and marls hosting many levels with nodular and tabular silicifications (Tarriño, 2006).
Several of these horizons have flint with exceptional quality for knapping which have been exploited during Prehistory.
On the field, there are many stigmas of mining activities. In the site of Pozarrate (Grandival, Treviño), hillside mining dumps have been identified with crescent morphologies where we are currently carrying out an archaeological excavation. Until now, a very high number of flint fragments have been recovered (tens of thousands of evidences) and abundants remnants of mining extractive tools: dolerite hammers, flint hammerstones and fragments of deer antlers, etc (Tarriño et al., 2014).
It is indeed one of the few prehistoric flint mines dated in the Iberian Peninsula. The chronology obtained have confirmed a Neolithic affiliation for the crescent-dump, offering dates between 5000-4500 (Cal. BC). The information obtained by the study of provenances of Raw Materials during the Upper Pleistocene and the Holocene indicates that Treviño flint have been circulated hundreds of kilometers through archaeological sites of the Cantabrian, the western Pyrenees and the South of the Aquitaine Basin in southwest of France (Tarriño et al., 2015).
