“Multi-method-approach” has now been for many years the buzzword in marble provenance analysis. Nevertheless a true combination of the results of different analytical methods is rarely applied in the sense of the combined simultaneous use of a large number of analytically obtained numerical variables. It is demonstrated here that the combination of data from isotope analysis, chemical data, and data from the chemical analysis of inclusion fluids of an artefact and of course in combination with a corresponding database enhances substantially the accuracy of marble provenance analysis. It is explicitly pointed out that the unchallenged collection of data of the chemical composition of marbles from different sources (and different analytical procedures) most probably implies severe differences in their comparability. Exemplarily presented is the nearly perfect discrimination of the most important fine-grained marbles and furthermore the possibility of the intra-site discrimination of the three Carrara districts and the assignment of two portrait heads to the Carrara Torano quarries.

多年来，“多种方法”一直是大理石来源分析的流行词。然而，在同时使用大量分析获得的数值变量的意义上，不同分析方法的结果的真正组合很少被应用。这里证明，来自同位素分析的数据、化学数据和来自人工制品的包裹体流体的化学分析的数据的组合，当然与相应的数据库的组合，大大提高了大理石来源分析的准确性。明确指出，毫无争议地收集不同来源（和不同分析程序）的大理石化学成分数据很可能意味着它们的可比性存在严重差异。典型的例子是对最重要的细粒大理石的近乎完美的辨别，此外还可以对三个卡拉拉地区进行现场辨别，并将两个肖像头像分配给卡拉拉托拉诺采石场。
