title: Identification of different types of imperial age marble finds using instrumental chemical analysis and pattern recognition analysis.
abstract: A physical-chemical characterisation of several marbles frequently used in ancient times for artistic or decorative purposes was performed in support the work of historians and restorers. The data were obtained using several different types of instrumental chemical methods (Thermogravimetry, Differential Thermal Analysis, X-ray Diffractometry and ICP Plasma Emission Spectroscopy) and have been summarised in short tables. The data have already proved useful in the identification of a small number of finds (statues or architectonic elements) from Ancient Rome (Imperial Age, 2nd-3nd cent. A.D.) for the purpose of which also a well-known pattern recognition analysis software package was used for data processing. In practice, the research showed that an organised set of chemical data obtained using several modern instrumental methods can provide a valid basis for the reasonably rapid and reliable identification of the type of marble used to make artistic artifacts that have not yet been subjected to typological study.
