Lithotheque of siliceous rocks of the Iberian northeast
This reference collection concerns the availability of siliceous rocks in NE Iberia, covering an area surpassing 32,000 km2. Collections are documented according to their geological frame and samples have been characterized from the point of view of its mineralogical, petrological and geochemical properties. We thus handle a large variety of documentary evidence such as maps, stratigraphic logs, photographs or laboratory reports. All these samples and data are being installed so they can be accessible to users either in person or virtually. So far we have attested 70 geological units offering flint layers with 86 lithotypes substantiated.
