Figure 8
From: A 36,200-year-old carving from Grotte des Gorges, Amange, Jura, France
Raman spectra of the red particles present inside the notches arranged radially around the concavity of the Grotte des Gorges figurine. Representative Raman spectra of the red particles observed in the notches (top), compared with the reference spectra of hematite extracted from the RRUFF database (bottom). The position, width and relative intensity of the measured signal matches the reference spectra for hematite.
