Abstract

Mortar samples from the remains of a nearly vanished structure in the village of Magán (Toledo, Spain) have been investigated. Their mineralogical and chemical composition have been analyzed to understand the building technology of their historical period and the functionality of the original structure. Furthermore, a wide range of characterization techniques has been employed in the investigation regarding the amount of information they can provide and assess their effectiveness in the field. Chemical characterization of the mortar samples has been performed by XRD and XRF and completed with TGA studies. FTIR and Raman Spectroscopy, together with ²⁸Si and ²⁷Al-MAS-NMR and Microscopy Studies complete these characterization studies. Although the samples possess similar composition, since the predominant mineralogy is quartz, feldspars, and phyllosilicates, the differences discovered let us establish a relationship between chemical data and petrographic mineralogical data, and the source of materials.

分析马甘（西班牙托莱多）历史建筑中的石灰砂浆：矿物学和烧制温度的启示

我们对来自马甘村（西班牙托莱多）一处几近消失的建筑遗迹的灰泥样本进行了调查。通过分析其矿物学和化学成分，了解了历史时期的建筑技术和原始结构的功能。此外，在调查中还采用了多种表征技术，以了解这些技术所能提供的信息量，并评估其在现场的有效性。通过 XRD 和 XRF 对灰泥样品进行了化学表征，并完成了 TGA 研究。傅立叶变换红外光谱和拉曼光谱，以及 28Si 和 27Al-MAS-NMR 和显微镜研究完成了这些表征研究。虽然样品的成分相似，因为主要矿物成分是石英、长石和植硅酸盐，但所发现的差异让我们确定了化学数据与岩相矿物学数据以及材料来源之间的关系。

期刊介绍： Journal of Archaeological Science: Reports is aimed at archaeologists and scientists engaged with the application of scientific techniques and methodologies to all areas of archaeology. The journal focuses on the results of the application of scientific methods to archaeological problems and debates. It will provide a forum for reviews and scientific debate of issues in scientific archaeology and their impact in the wider subject. Journal of Archaeological Science: Reports will publish papers of excellent archaeological science, with regional or wider interest. This will include case studies, reviews and short papers where an established scientific technique sheds light on archaeological questions and debates.
