This PhD thesis is focused on methodology for the provenance determination of marbles from historic quarries and marble artefacts, respectively. Various petrographic, geochemical, and physical data were compiled to distinguish among different marble types, as well as to explore the suitability and limits of experimental techniques for such provenance studies. Moreover, by comparing the data obtained with the results from the artefacts the importance of the selected methodology was tested in detail. The correct determination of the source locality for marbles represents a difficult task, due mainly to both the variable characteristics of marbles coming from any one locality; and the converse, the similarity in properties between samples from different areas. Facing this complex situation, a multivariate approach proved to be necessary. Most of the previous analytical studies on marble provenance have been conducted on pure white marbles from the Mediterranean area where the methodology, based upon a combination of various mineralogical-petrographic and chemical criteria, was originally established. However, the Czech Republic is also rich in 'impure' crystalline limestones containing common noncarbonate admixtures (e.g. silicates, magnetic minerals, and carbonaceous matter) which led to the...
