A New Approach for Provenance Studies of Archaeological Finds: Inferences from Trace Elements in Carbonate Minerals of Alpine White Marbles by a Bench-to-Top μ-XRF Spectrometer

Table 2

Measured μ-XRF elements: mean and standard deviation (σ) values are calculated from a variable number of diffraction free spectra reported in # points column.
