Study of color pigments associated to archaic chinchorro mummies and grave goods in Northern Chile (7000-3500 B.P.)

This article presents the results of physical-chemical characterization of the layers of coating covering the bodies, faces and stuffed of four mummified human bodies and seven grave goods from the Chinchorro Archaic funerary tradition that inhabited the Atacama Desert of the far northern coast of Chile. Using Scanning Electron Microscopy with Energy-Dispersive X-Rays (SEM-EDX) and X-Ray Diffraction (μDRX), the study identified the use of different pigments including iron, manganese and copper oxides that were combined into different preparations or pictorial recipes for paste and coating bodies and faces. The results indicate that the Chinchorro, an archaic hunting, gathering and fishing society (7000-3500 B.P.) managed a complex color technology for their mortuary practices.
