Lithic materials in archaeological records have always been the object of special attention by archaeologists, especially from prehistoric contexts. They draw such attention thanks to their often excellent preservation, and the information that the intrinsic characteristics of the rocks can yield about past behaviors including mobility of goods and people through chemical analysis and provenance studies. Although they do not represent the majority of the artifacts recovered from precolonial archaeological sites in the Lesser Antilles, their diversity necessitates varied knowledge, methods, and skills to be studied. Here, we present preliminary results from lithic specialists in characterization of volcanic rocks, diorite, turquoise used for bead production, and silicites.Several volcanic glass artifacts have been identified for the first time from Saladoid sites from Guadeloupe and Dominica. However, many questions remain about the geological origin and the petrogenesis of these artifacts given their very specific chemical composition. On the other hand, detailed microtextural and micropaleontological studies of the different siliceous raw materials provide first results identifying and mapping their origin and distribution among the Caribbean islands. As a first glance of what will become a long-term project, results presented in this paper demonstrate the capacity of petrological studies carried out with appropriate technical methods to help us improve our knowledge of the Ceramic Age populations’ movement and rock distribution networks.< Réduire
