The development of raw material characterisation in Palaeolithic Archaeology in the last fifty years has widened our knowledge about the societies who inhabited Europe in the past. The characterisation of raw material, specially flint, has allowed defining the mobility of stones and people, selective processes to obtain specific varieties and proto-mining or mining activities. It also enables the researchers to a better understand knapping or use properties of specific raw materials. Quartzite was the second most-often used lithic raw material in Europe in the Palaeolithic. However, this rock has not been characterized fully from the geo-archaeological point of view. The main aim of this presentation is present partial results of my recently defended PhD, focussed in the understanding of acquisition, distribution and management mechanisms implemented by Middle-Palaeolithic societies in the Cantabrian Region (Asturias and Cantabria communities, NW Spain) to exploit quartzite. To do so, we are going to present the data of two middle-Palaeolithic archaeological sites: El Habario and El Arteu. We also present through a comprehensive way, the quartzite distribution in the area: The Deva, Cares and Güeña valleys. Finally, and due to the scarcity of previous research on the properties of this raw material, we also present the characteristics of these quartzites from a geo-archaeological point of view. The methodology used for this research combines three different approaches: microscopic, macroscopic and regional scales. The first one is based on petrographic, geochemical and binocular characterisation. The second, is the macroscopic approach and it is founded on the analysis of lithic assemblages based on technological, typological, petrological and metric criteria. The same macroscopic approach is used to characterise the potential raw material acquisition areas through the geological survey of the geological strata and deposits where quartzites are present. Finally, the regional scale is based on the geographic, geologic and archaeological analysis of landscape, mainly using Geographic Information Systems. The application of this comprehensive methodology to a narrow area, the Deva, Cares and Güeña valleys, allow us to understand quartzite from geological and archaeological perspectives. On one hand, we surveyed the source area of the sediment which formed the “archaeological quartzites”, their transformations due to sedimentary and metamorphic forces, and the mineralogy of these rocks according to the different geological environments where quartzites were formed. The understanding of all these phenomena allows us to classify quartzite into seven petrogenetic types and varieties, according to grain size and mineralogy. We also describe the geological strata where quartzite is present, characterising both their arrangement and its dispersion based on the types and varieties defined. On the other hand, we inferred the acquisition, management, and mobility patterns of Prehistoric societies in the Deva, Cares and Güeña valleys during the Middle Palaeolithic based on the analysis of the lithic assemblages from the archaeological sites of El Habario and El Arteu. This allowed us to understand the different strategies of landscape management of such a heterogeneous and mountainous area as the central Cantabrian Region is. The exploitation of quartzites in the sites of El Habario and El Arteu allow us to understand the dialectical territorial management of this mountainous area through the combination of selective processes and mobility mechanisms in lower and middle altitudes. These perspectives let us to understand this mountainous region not as a barrier but as an environmental-mosaic managed and optimised by Middle Palaeolithic societies. In addition, the recognition of the quartzite types using non-destructive methods in both complete assemblages through comprehensive analysis, lets us to understand preferential catchment and management of specific quartzites and different behaviours. Among others, a) adaptable mobility patterns and selection of specific types of quartzites; b) Complex management of lithic mass based on stock creation; or c) tool-kit maintenance on certain quartzite types and the dismissal of others.
