The Neolithic Flint Quarry of Pozarrate (Treviño, Northern Spain)

Abstract

In this work, we present the preliminary data we have obtained in the Neolithic flint quarry of Pozarrate, currently under archaeological works. We want to put forward an update about the sedimentary fillings of one of the crescent-shaped dump quarries (6000-5600 BP). It is located at the Sierra de Araico-Cucho (Trevino, northern Spain). In this region, Tertiary carbonated terrains which host important silicifications called Trevino flint (Tarrino, A. (2006). El silex en la cuenca vasco-cantabrica y Pirineo Navarro. Caracterizacion y su aprovechamiento en la Prehistoria. Monograia 21, Museo Nacional y Centro de Investigacion de Altamira. Madrid: Ministerio de Cultura) are outcropped. The procurement of these silicifications by prehistoric populations was motivated by the good quality of this raw material for knapping. Currently, it constitutes one of the few Neolithic known flint mines of the Iberian Peninsula, understood as places of exploitation of flint with landscape modifications. Some instruments related to prehistoric quarry works have been recovered, such as picks, maces, and hammers made of flint, dolerite, and deer antler.

Studies on Pozarrate material remains have been conducted in an interdisciplinary way, in order to have a better understanding of the prehistoric mining processes. Several methodologies are being used in the study of the lithic industries, including flint characterization, procurement, typological, typometrical, technological, and functional approaches. We have obtained the initial data about extraction, selection, management, and use processes of the flint and dolerite assemblages. Deer antler remains have recently undergone a restoration process and preliminary data have been offered. Moreover, an experimental approach has been applied to clarify specific archaeological issues and technical solutions for quarrying using dolerite maces.
