- •
Samples of prehispanic rock art from Oyola's archaeological site have been analyzed.
- •
The pigments employed were characterized using micro-Raman spectroscopy, SEM-EDS and BSD, and optical microscopy.
- •
Red colors were attributed to hematite, white to gypsum and black to graphite.
- •
A methodology to characterize carbonization deposition layers in stratigraphies was developed.
- •
This methodology allows performing relative and absolute chronology of archaeological events.
