RAMAN SPECTROSCOPY AND X-RAY FLUORESCENCE IN MOLECULAR ANALYSIS OF YELLOW BLOCKS FROM THE ARCHEOLOGICAL SITE PLAYA MILLER 7 (NORTHERN CHILE)

Yellow blocks from the archaeological site Playa Miller 7 (PLM7), on the coast of Atacama Desert in northern Chile, were analyzed by Raman spectroscopy and X-ray fluorescence (XRF) portable. Our results identify for the first time the use of K-jarosite and natrojarosite in prehispanic times (approx....
