BOOK DESCRIPTIONThe Union Internationale des Sciences Pré- et Protohistoriques (UISPP) commission on Flint Mining in Pre- and Protohistoric Times was created at the 12th meeting of the European Association of Archaeologists (Cracow, Poland, 19th-24th September 2006). The aim was to perpetuate the tradition of organizing international symposia on flint, established by the Limburg Branch of the Dutch Geological Society in 1969 at Maastricht. The commission intends to maintain cooperation in archaeological research on siliceous rock mining (flint, chert, hornstone, radiolarite, jasper and obsidian), by presenting and discussing methods and results. Major fields of interest include the different stages of chaînes opératoires of manufacture, specialisation of labour and circulation of raw materials, as well as the study of flint mining sites in relation to pre- and protohistoric settlement patterns. The objective of the commission is to promote these lines of research into flint mining and its methods, thus enabling a better understanding of the various phenomena and processes taking place in pre- and protohistoric times. This volume contains the papers of the Paris conference held on 10th-11th September 2012, together with some additional papers presented at Vienna 2010 and Florianópolis 2011. A first set of contributions concerns the main topic of the conference, which was lithothèques and reference collections. A further group of papers concerns the second conference theme: workshops, from excavation to chaînes opératoires reconstruction.
