Abstract

ABSTRACT Solid-state nuclear magnetic resonance, which enables the characterization of structures of a variety of materials whatever their crystallinity/amorphous state, is used in the present work to determine the provenance of two raw materials, namely marbles and cherts. Regarding marbles, the 13C NMR signal of the carbonate function contains information about both the Fe content in its area and the presence of calcium substitutions in the calcite crystal in its linewidth. Regarding cherts, discriminant information is provided by both 29Si and 27Al NMR: the 29Si area signal depends on the paramagnetic ion content of the material, and the 27Al spectra give information both on the aluminosilicate content and its distribution in tecto- and layer-lattice aluminosilicates. As an application, we use the differences observed from one source to another to determine the provenance of archaeological finds. GRAPHICAL ABSTRACT
采购和核磁共振:旧材料的新应用
固态核磁共振能够表征各种材料的结构,无论其结晶度或非晶态,在本工作中用于确定两种原材料的来源,即大理石和燧石。对于大理岩,碳酸盐函数的13C核磁共振信号包含其区域内的铁含量和方解石晶体线宽中钙取代的存在信息。对于燧石,29Si和27Al核磁共振都提供了判别信息:29Si区域信号取决于材料的顺磁离子含量,27Al光谱提供了硅铝酸盐含量及其在构造和层晶格硅铝酸盐中的分布信息。作为一种应用,我们使用从一个来源到另一个来源观察到的差异来确定考古发现的来源。图形抽象
