The ancient city of Byblos (Jbail, Lebanon) provides one of the primary examples of urban organization in the Mediterranean world. This multimillenary city bears an exceptional testimony to the beginnings of the Phoenician civilization. The site covers an area of 10 ha located along the coast. The present paper deals with the synthetic mapping of the archaeological site and its environment using remote sensing techniques. Very high resolution imagery is vital for monitoring any archaeological site in its widest context. In the specific case of Byblos the comparison of the Orbview 3, Ikonos 2 and Geo-Eye 1digital data indicates that a spatial resolution of about half-a-meter is necessary for archaeological purposes and particularly for mapping the walls and the buildings. The use of Corona archive acquired in 1970 allows mapping the archaeological site and its coastal environment before the Lebanese civil war. This multitemporal approach allows us to evaluate the sensitivity of the archaeological site to external factors such as the coastal erosion, the cliff degradation, and the urban growth. It also helps to better plan the improvement of the site for touristic purposes.

Na base do monte Lípez (Província Sud-Lípez, Dpto. Potosí, Bolívia) estão preservados vestígios de assentamentos, ranchos e instalações produtivas que estiveram associadas como produção minerária e metalúrgica no período colonial, e possivelmente antes dele. Inesgotável fonte de tesouros ocultos para a população local povoados fantasmas para os raros turistas que passam por ali, estes testemunhos materiais constituem uma fonte de informações excepcional para o estudo tanto do passado como do universo da produção de metáis. Com efeito, apesar de sua distância e rudeza climática este enclave mineiro foi o cenário onde ocorreram intensos, quando não violentos, fatos em torno do controle tanto das jazidas minerais como os espíritos humanos. Realocação de povos indígenas, destruição de assentamentos e extinção de antigos cultos, rápidas mudanças produtivas, transformações de paisagem etc. Em seu conjunto estes fatos mostram uma síntese da empresa colonial nesta região dos Andes. À luz de novos dados e de uma perspectiva multidisciplinar (história, arqueologia, arqueometria e teledetecção) trataremos das paragens que conformaram San Antonio del Nuevo Mundo. O estudo de caso abre debate sobre a articulação entre as fontes históricas e o registro arqueológico, tanto seus encontros e complementaridades como seus desencontros e silêncios.

The Pays re´mois in the eastern Paris Basin is an administrative area of 1394 km2; in the surroundings of Reims (France). Two main geological substrata are separated by the Iˆle-de-France cuesta: the Tertiary substratum in the western part is composed of various types of geomaterials (clay, sandstone, limestone, burrstone), whereas the substratum in the eastern part is composed only of Cretaceous Chalk. A field survey in each commune of the Pays re´moisidentified 26 building materials documented in a Geographic Information System database (GIS-database) that includes information about them (lithology, petrographical and petrophysical data, weathering) and the corresponding buildings (e.g. town, georeferenced data, building type, position on the fac¸ade). The spatial analysis of the building materials’ distribution (Standard Deviational Ellipse) with GIS identifies their uses and the criteria established for the selection of the materials: availability, efficiency, workability and durability. Some lithologies were preferred for particular buildings or selected for their efficiency in specific positions. The study also defines the relation between the stones’ origin (local and non-local stones) and their application. This database is useful to establish stone replacement strategies in the Pays re´mois
