| Sumario: | [EN] The Neolithic groups that settled in La Draga exploited a wide range of rocks and minerals to produce the different stone utensils needed for their subsistence and artisan work. This diversity of lithologies responds to the different types of instruments and the functions far which they would be intended. Three large groups of tools made with different types of rocks can be differentiated. The chipped tools were made from siliceous rocks, basically flint and quartz. Among the adzes, which have a bevel produced by polishíng two opposing surfaces, such metamorphic rocks as amphlbole and corneal schists are documented. Among the instruments of greater volume used for grinding, such as querns, the use of basalts, porphyric rocks and granites is documented. Fínally, sandstone was used for polishing other materials, while limestone pebbles were used far burnishing. The origin of ali these subjects shows a very broad catchment area. Most rocks come from a local environment, where quartz, basalt, porphyric rock, sandstone and limestone can be faund. Others come from a regional context that required traveling several tens of kilometers far their supply; for example, the amph'ibolic shale comes from the Guilleries, Albera Massif or Cap de Creus, while the cornean comes from the foothills of the Pre-Pyrenees, and granites from the axial Pyrenees or the Guilleríes and the Gavarres massifs. However, other rocks such as flint and jasper, have a distant origin, more than 110 km away, both to the north (flint from the Narbonne-Sigean basin, France) and south (jaspers from the mountain of Montjuïc in Barcelona). |
