The composition of rock-painting pigments from Egypt (Gilf Kebia area) has been analyzed by means of molecular spectroscopy such as Fourier transform infrared and micro-Raman spectroscopy and scanning electron microscopy coupled to an energy dispersive X-ray spectrometer and X-ray fluorescence analysis.Red and yellow pigments were recognized as red and yellow ochre with additional rutile.
Graphical abstractFigure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Prehistorical red and yellow pigments from Egypt are ochres with additional rutile. ► Al, Si, Ti and Fe are the major components, with small amount of Ca and traces of Mn. ► The pigments contain high percentage contributions of Si-rich and Al–Si-rich particle types. ► Iron oxides and titanium oxide are present like incorporations into grains of aluminosilicates.
