A multi-analytical evaluation of the depositional pattern on open-air rock art ...

Microscopic observation correlated with chemical-mineralogical characterization was performed on pigment samples from "Abrigo del Lince" rock art site (V-IV millennium BC), in order to provide contributions to the study of prehistoric schematic art on granite in the province of Badajoz (Spain). The research objectives include the understanding of technological and cultural aspects, as well as of conservation an...

Geochemistry of phosphatic nodules as a tool for understanding depositional and...

Interpreting depositional settings of cave sites is generally problematic, especially in absence of paleontological/archaeological evidence. This is the case of some deposits at San Teodoro Cave (Sicily), a key site for the Mediterranean Paleolithic. In a stratigraphic level interrupted by a carbonatic concretion, phosphatic nodules are present only in the part enclosed between the concretion and the cave wall....

International meeting on paleoclimate: change and adaptation

Climate is the planetary response of the atmospheric circulation to its changing composition, to the solar system configuration, to the Earth’s rotation and to the oceans’ and continents’ distributions. It displays, as a result, a restless moving pattern, expressed at a global scale by subsiding and uplifting convection cells. These changes have long been recognized and documented in geologic objects of all age...

Past climate changes and human adaptation

Climate is the planetary response of the atmospheric circulation to changes in its composition, the solar system configuration, Earth’s rotation, and the distribution of the oceans and continents. As a result, it is continuously evolving, expressed at a global scale by subsiding and uplifting convection cells. These changes have long been recognized and documented in geologic objects of all ages. There are clim...

Pigment in Western Iberian Schematic Rock Art: An analytical approach

This paper explores the processes involved in the production of prehistoric paintings using inorganic pigmentation. The focus for discussion involves a number of rock-shelter sites that contain rock art within the western part of the Iberian Peninsula, with particular reference to the sites that contain Schematic rock art. A direct date cannot be obtained on rock art that is made with inorganic pigments. Howeve...

Natureza e processamento de pigmentos de pinturas rupestres

Pinturas Rupestres: Matérias-primas, Técnicas e Gestão do Território

Um dos aspetos mais interessantes nos variados estudos dos pigmentos utilizados para a realização de pinturas rupestres é a seleção e manipulação das matérias-primas. Para estes estudos têm que ser consi-derados os aspetos geológicos, relacionados com a disponibilidade de matérias-primas, os aspetos culturais, resultantes das diferentes tradições adotadas e finalmente, os aspetos relacionados com a conservação,...

Caracterização de pigmentos em arte rupestre

A arte rupestre é o estudo dos padrões de antropização da paisagem e pode ser um importante contributo para uma aproximação ao universo sócio-cultural das comunidades pré-históricas. A arte esquemática pintada é parte do ciclo artístico pós-Paleolítico e uma das suas características é o tipo de técnica de execução. Um conjunto de diferentes estudos complementares está a ser realizado em vários abrigos pintados ...

Interpretation of clay mineral associations of Quaternary sediments at Alto Rib...

Research has been carried out in Alto Ribatejo (central Portugal, western Iberia) with the purpose of contextualizing Late Pleistocene and Early Holocene archaeological remains within the coeval landscape. Several regional Quaternary deposits were analysed in terms of their sand fraction mineralogy (microscopic observation) and clay mineralogy (X-ray diffraction of orientated aggregates). The sedimentary record...
