Ancient quarries are intriguing archaeological sites, but their detailed recording is complex. This paper presents a cost-effective approach to mapping of the Roman quarry site of Pitaranha (Portugal-Spain). First, aerial photographs were acquired using a radio-controlled digital reflex camera attached to a Helikite, which allowed the acquisition of the necessary low-altitude aerial footage in the very unstable wind conditions above the quarry. Using computer vision algorithms, the resulting set of photographs was semi-automatically transformed into a Digital Surface Model (DSM) and a corresponding orthophotograph. Besides focusing on the acquisition and processing method, this paper evaluates the accuracy of the generated products. The orthophotograph proved to be satisfactorily accurate for 1:200 hard-copy mapping. [ABSTRACT FROM AUTHOR]

This paper focuses on plain, stylistically unvaried pottery from three Late Neolithic sites from the Mondego Plateau, Portugal, and investigates ceramic production and exchange among small-scale prehistoric societies by means of thin-section petrography and chemical analysis (INAA). The results show that the majority of the pottery was made with widely available, granite-derived sedimentary clays, but petrographic differences between fabrics indicate collection at multiple locations within these deposits. Variation in chemical composition is consistent with site-specific sourcing areas, while comparison with data from earlier sites in the Mondego and surrounding mountains suggests that such sources were geographically restricted within the plateau. In contrast, the small percentage of vessels produced with residual clays of metamorphic and intermediate igneous origin, which outcrop over 10 km and 30 km from the archaeological sites, demonstrates that plain pottery did circulate during the Neolithic beyond the funerary sphere. This is the product of the routines of mobility and social networks of Neolithic groups across the wider landscape, which involved the exchange of 'mundane' vessels. Finally, the study demonstrates that micro-regional provenance studies can provide significant insights into prehistoric social landscapes if the data are interrogated beyond simplistic classifications of local and non-local.
