Disponibilidad de rocas silíceas en el noreste peninsular: resultados del proyecto LITOcat

On the occasion of the LITOcat Project a reference collection concerning the siliceous rocks from north-eastern Iberia has been constituted with archaeological aims. We introduce here a first systematic record regarding those geological units in which siliceous rocks occur, notwithstanding whether they were used or not as raw material throughout Prehistoric times. All these rocks have been contextualised from the point of view of its geological frame, unit and formation age, as well as the environment where it was set up. All of that contributes to obtain a first approach about the availability of siliceous rocks in north-eastern Iberia. In the near future the project will progress with the edition of a digital map regarding the geological units containing flint layers and, afterwards, the cycle will closure with a catalogue including all the types of flint that appear into the region as well as its corresponding petrological characterization.
