L'utilisation de ces matériaux nécessitait l'élaboration de chaînes opératoires de production qu'il a été possible de reconstituer à travers l'étude des matières colorantes provenant des sites solutréens de Combe Saunière (Dordogne), Fressignes (Indre) et Les Maîtreaux (Indre-et-Loire). L'hématite, produisant une poudre rouge, et les oxydes de manganèse, produisant une poudre noire, sont les matières colorantes préférentiellement recherchées par les Solutréens. Il a été possible de mettre en évidence le chauffage des matières colorantes jaunes, qui a pour but la production d'hématite. À Combe Saunière et à Fressignes, le contexte ne permet pas de trancher en faveur d'un chauffage volontaire. En revanche, sur le site des Maîtreaux, une aire de 20 m 2 environ c...

Bone remains are often the unique witnesses of ancient societies and so an irreplaceable source of information about ages, populations, ancient diets and palaeoclimates. As their degree of conservation is highly variable and dependent on the environment, the alteration processes, especially the modifications due to transport of chemical species, should be known in order to get reliable information on the past. Analysis of the literature and experimental results allows to describe the main features of the diagenetic evolution and to determine the important parameters for an adequate diffusion model We show that a more precise interpretation of the uptake of chemical species in archaeological bone will be possible when the complex organic and mineral microstructure of bone will be understood and if more diffusion coefficients of different chemical species in bone are determined.

However, they alter over time. Alteration occurs at all scales from the macroscopic to nanoscopic level. The evaluation of information extracted on palaeodiets, ages and palaeoclimates from their chemical and isotopic composition requires the study of diagenetic modifications by means of different complementary analytical methods. Diagenetic parameters that quantify the post-mortem alteration of bone are bone histology ...

This study deals with identification of manganese oxides in black pigments by micro-XANES (X-ray absorption near-edge structure) based on previous TEM (transmission electron microscopy) studies. Complex mixtures of the manganese oxides studied are present in some of mankind's oldest known paintings, namely those from the caves of Lascaux (Dordogne, France) and Ekain (Basque country, Spain). Scarce manganese oxide minerals, including groutite, hausmannite, and manganite, were found for the first time in Paleolithic art at these archaeological sites. Because there are no known deposits of such minerals in these areas, more distant origins and trade routes are inferred. The closest known Mn-rich geological province for Lascaux is the central Pyrénées, which is ~ 250 km from the Dordogne area.
