The study of the provenance of dolomitic marble artefacts has become relevant since it was discovered that quarries of this marble other than that of Cape-Vathy located on the island of Thasos have been exploited since Antiquity. To improve our knowledge about the provenance of materials and the extent of their dispersion, multiple archaeometric studies were performed in the past including isotope analyses, petrography, cathodoluminescence, and elemental analyses. In the present work, solid-state nuclear magnetic resonance (NMR) spectroscopy has been added to this panel of techniques. NMR allows the characterization of the material at a molecular level by looking at different nuclei: carbon, magnesium, and calcium. Statistical analysis of the data collected on both quarry samples and archaeologic items was also implemented and clearly demonstrates the efficiency of a holistic approach for provenance elucidation. Finally, the first Mg NMR tests have shown the potential of this technique to discriminate between dolomitic marbles of different provenance. The results are discussed in terms of their historical meaning and illustrate the exploitation of sources of dolomitic marbles other than the Greek Thasos source.
自从发现除了位于萨索斯岛的瓦西角的大理石矿以外，这种白云石大理岩制品的其他采石场自古代以来就已被开采后，对白云石大理岩制品来源的研究就变得很重要了。为了增进我们对材料来源及其散布范围的了解，过去进行了多项考古测量研究，包括同位素分析、岩相学、阴极发光和元素分析。在本研究中，固态核磁共振（NMR）光谱学已被添加到这一系列技术中。核磁共振通过观察不同的原子核：碳、镁和钙，能够在分子水平上对材料进行表征。还对采石场样品和考古物品收集的数据进行了统计分析，这清楚地证明了采用整体方法来阐明来源的有效性。最后，首次进行的镁核磁共振测试显示了该技术区分不同来源白云石大理岩的潜力。将根据其历史意义对结果进行讨论，并说明除了希腊萨索斯岛来源之外的白云石大理岩来源的开采情况。
