This work presents a geological approach to the characterization of lithic materials collected at the Mesolithic Sado River’s shell middens, located between Alcácer do Sal and São Romão do Sado, 80 km SE of Lisbon. These shell middens contain abundant lithic materials from different lithologies, including mainly Siliceous Slates, Chert, Jasper and Quartz. A first look at the geological map pointed to a provenan...
ABSTRACT The Sado River Drainage Survey project (2004-2008) was designed to fill a significant gap in our knowledge of the prehistory of Portugal. Southern Alentejo constitutes nearly one third of the total land mass of continental Portugal, but has received comparatively little attention from Palaeolithic archaeologists. Practically nothing was known about the prehistory of the Sado River basin, which includes...

During the last three years geoscientists of various institutions have developed a project aiming the setup of a geoconservation strategy in Portugal (Brilha, 2009). One of the main goals of the project was the establishment of an inventory of the most important Portuguese geosites, under the scientific point of view. In a near future, national authorities will consider this inventory as a technical support for...
