S Minor and trace elements (K, Sr, Ba, Al, Fe, Mn, Si, Ti) have been measured in marbles from classical mediterranean quarries (Afyon, Denizli, Aphrodisias, Ephesus, Marmara and Carrara). A distinctive characterization of the classical marble sources by means of such chemical parameters seems very difficult, although some distinctions can be attempted between a few different areas and zones, within an area.

The AA. illustrate the results of the analyses, by fluorescence X-ray and refractive index, of obsidians both from source areas of central and eastern Anatolia and from late-chalcolithic levels of Arslantepe (Malatya, Turkey). These levels are characterized by a large prevalence of eastern obsidians from many source areas; therefore their evidence fit in the pattern of diffusion outlined for the Chalcolithic by previous authors.
