This special volume of Quaternary International is the result of the rich discussions given in the Symposium “Desde las fuentes: el aprovisionamiento de rocas como problematica arqueol ogica ” which was held at the XVIII National Congres of Argentine Archaeology, in the province of La Rioja in 2013. It compiles the work of different research teams which investigate throughout Argentina, in different natural and social landscapes of Patagonia, the Pampas and the Northwestern region of the country. These papers show a multiplicity of theoretic positions on technology, a wide range of topics addressed and the use of distinct methodologies and techniques. However, they share their interest for ancient ways of life and the processes of selection, acquisition, and preparation of raw materials by past societies.
