X-ray Diffraction / Scanning electron microscopy

A mineralogical analysis with x-ray diffraction on dust of archaeological materials was performed by hiring the X-ray Diffraction Area from the School of Chemistry of the UCR. Sampling of the spheres on archaeological sites on the southern part of the country and in San José resulted in a mineralogical characterization, according to the diffraction patterns analyzed in the samples.

The patterns’ data will be subsequently transformed into a numerical data matrix, to apply a series of statistical analysis. The data should enable the analysis of the main components and conglomerates, to determine the possible relations between the spheres.
