Abstract

Three pictographs from the Tito Bustillo cave have been studied by Raman microspectroscopy, infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy and scanning electronic microscopy combined with energy dispersive X-ray spectrometry. All the samples can be associated with the oldest cave decoration phases. Haematite of two granular sizes (<1 and <10 µm) is the main component of the pictographs. Hydroxyapatite, anatase and amorphous carbon appear as additional components in some of them. Calcite, α-quartz and clay minerals are used as filler materials. No organic binders have been detected. Considering the main components, granular size, and secondary phases of the pigments it is concluded that the ochre quarry of the cave was not used to make the paintings of this chronology. Two of the analysed figures of this cave seem to have been painted with the same type of paint.
