Inscripción de trabajos en el International Symposium on Knappable Materials (Barcelona 2015).

International Symposium on Knappable Materials: ‘On the Rocks’. 
University of Barcelona, Spain, 8–10 September 2015 
http://www.ub.edu/cherts-symp2015/ 

As far as raw materials go, chert and other knappable stone stand out as some of the most common materials in the archaeological record, sometimes the only preserved material. They were used in almost every corner of the world, from the Palaeolithic up until today. Use of these materials even predates the appearance of our species. Being so widespread, geographically and chronologically, this topic merits a global meeting of researchers. 
This symposium will cover all aspects of knapped stone raw materials from geological origin, to mining, usage, and laboratory analyses on these materials. Although we expect more focus on chert and other microcrystalline quartz varieties, we also encourage presentations related to other knappable materials such as obsidian, quartzite, rhyolite. Papers will be accepted on any culture or period, whether you are a field archaeologist, laboratory researcher, ethnographer or a modern day knapper. 
Main Sessions: The symposium will focus on two major themes: (1) the chaîne opératoire of knapped stone artefacts, and (2) auxiliary sciences related to lithics. Themes and sessions are listed in the symposium webpage 
Abstracts: Deadline is 28 February 2015. Form: http://cherts-symp2015.net/?page_id=45.
