“…The calcite grain size evolution on Naxos shows a typical trend in an Arrhenius type diagram ( Fig. 7; Ebert et al, 2010;Herwegh et al, 2011). This fits well with the observation of calcite grain sizes in tectonic settings characterized by high strain deformation (Ebert et al, 2007;Herwegh et al, 2011).…”

Dolomitic marble on the island of Naxos was deformed at variable temperatures ranging from 390°C to >700°C. Microstructural investigations indicate two end-member of deformation mechanisms: (1) Diffusion creep processes associated with small grain sizes and weak or no CPO (crystallographic preferred orientation), whereas (2) dislocation creep processes are related with larger grain sizes and strong CPO. The change between these mechanisms depends on grain size and temperature. Therefore, sample with dislocation and diffusion creep microstructures and CPO occur at intermediate temperatures in relative pure dolomite samples. The measured dolomite grain size ranges from 3 to 940 µm. Grain sizes at Tmax >450°C show an Arrhenius type evolution reflecting the stabilized grain size in deformed and relative pure dolomite. The stabilized grain size is five times smaller than that of calcite at the same temperature and shows the same Arrhenius-type evolution. In addition, the effect of second phase particle influences the grain size evolution, comparable with calcite. Calcite/dolomite mixtures are also characterized by the same difference in grain size, but recrystallisation mechanism including chemical recrystallization induced by deformation may contribute to apparent non-temperature equilibrated Mg-content in calcite.

NMR as a new tool for cultural heritage application: The provenance of ancient white marbles

Identifying the origin of marble used in antiquity brings back to light details of the economic, social and political organization of classical societies, and characterizing in depth the chemistry of marble is key to discovering its provenance. Beyond X-ray diffraction, which could reveal the presence of discriminant secondary crystalline phases and the quantification of accessory minerals combined with a multivariate analysis approach, solid-state nuclear magnetic resonance (NMR) enables one to recognize the local structure arrangement of both crystalline and amorphous materials by looking at one or more selected atoms. In present paper targets the 13 C nuclide, and thus the major component of marble, calcium carbonate. Whatever their geological origin, marbles 13 C-NMR spectra present only one resonance corresponding to the carboxyl function whose intensity and line width vary from one marble to another. If the variation of the NMR signal intensity observed is the result of great T1 variations (from 220 to 5300 s) and is linked to iron content, the line width reflects defects in the calcite crystal in which calcium has been replaced by another element such as magnesium, aluminium or strontium. The specific profile of the NMR signal has been used successfully to help determine the origin of some archaeological items.

“…Minero-petrographic, geochemical and provenance analyses of these marbles have great importance for historical and archaeological studies as well as for restoration of ancient artworks, monuments and buildings, and for determining imitations. In recent years, aimed to ascertain the provenance of marble sample of unknown origin, multiple analytical approaches have been performed to define a representative minero-petrographic, chemical-isotopic and physical database of the most important marbles used in antiquity [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”
