Abstract

Étude tracéologique de la perforation. Application aux perles gravettiennes de l'abri Pataud, du Blot, des Peyrugues Use Wear and Perforation Study. Application to Gravettian Beads from Abri Pataud, le Blot and les Peyrugues Jean Rodière * Résumé : Cet article a pour but l'étude des modes de perforation des perles préhistoriques par la détermination de dif érents paramètres, la vérii cation de la validité de ces dif érents paramètres par l'expérimentation, les analyses et comparaisons entre les perles expérimentales et les perles préhistoriques par les examens non destructifs au Microscope Electronique à Balayage (MEB) et au micro-rugosimètre. Abstract : h e objective of this article is the perforation process of the prehistorically beads by the determination of the dif erent parameters, the verii cation of the validity of dif erent parameters by experimentation, the analyses and comparisons between the experimental beads and prehistorically beads by the investigation of nondestructive technique with Scanning Electronic Microscope (SEM) and microtopography.

Informative Potential of Multiscale Observations in Archaeological Biominerals Down to Nanoscale

“…Similar rectangular beads as those found at Abri Pataud (Vercoutère et al 2011;Chiotti et al 2014;) have been discovered in two additional French sites known for the Final Gravettian period: at the rock shelter of Les Peyrugues (Allard et al 1997;Rodière 2011) and at the site of Le Blot (Chauvière and Fontana 2005). A closer look at these ornaments explains the difficulty of raw material identification and of the study of their use.…”

“…This analytical approach was also combined with experimentation to simulate the production process. Four steps of the chaine opératoire have been tested: (1) shaping, (2) perforation, (3) segmenting and (4) polishing (Rodière 2011).…”
