A method is proposed for the characterisation of marble samples used in historical build-ings in Bursa, Turkey. Determination of heavy metals such as Cu, Pb, Ag, Ni, Mn, Cd, Zn, Fe, Co and Mg in original marbles have been carried out by atomic absorption spectro-photometer, and Na and K by atomic emission spectrophotometer. Information about geographical origin is often required of marble samples. In order to obtain such information, principaI component analysis, correlation analysis and cIuster analysis techniques can be used as valid tools for processing series of data from chemical analysis. The techniques were applied to the raw and standardised data, showing different clusters related to the origin of marble sampIes. Some predictions about the origin of samples are made and showing the potential of chemometric techniques and their possible contribution to the characterisation of marbles used in historical buildings.

Analiza głównego czynnika, analiza korelacyjna i analiza kIasterów zostały wykorzystane do badania podobieństw chemicznych marmurów z różnych starożytnych budyn-ków w Turcji. Danymi do utworzenia odpowiednich matryc były wyniki oznaczeń Cu, Pb, Ag, Ni, Mn, Cd, Zn, F e iCo metodą AAS oraz Na i K metodą AES w próbkach marmurów. Przeprowadzona analiza chemometryczna pozwolił a na określenie miejsc pochodzenia marmuów.
