EDXRF DATA: An archaeological and archaeometric study of Late Punic-Roman Pottery from the Tas-Silġ Sanctuary and the Żejtun Villa, Malta

These datasets will be made fully accessible when the associated study is published. These datasets comprise Energy Dispersive X-Ray Fluorescence (EDXRF) raw data collected from Late Punic - Early Roman vessel sherds excavated at the Żejtun Villa and the Tas-Silġ Sanctuary archaeological sites in Malta. The data were analysed and processed by Emma Richard-Trémeau, Joseph Grech and Alexandra Humann as part of the 'Compiling Fabric Identity for Pottery from Maltese Sites' (CoFIPoMS) project under the supervision of Dr. Ing. John Charles Betts at the University of Malta. These datasets include readings for both pottery sherds and raw materials (local samples of clay). These datasets are compositional. This Zenodo entry contains: RAW DATA (Zip file): The raw data generated by the EDXRF for all samples analysed, expressed as oxides in %. Four spreadsheets are available: the data for the clays; the data for the pottery; and repeated readings for one sample of clay (QL.B1) and one sample of pottery (Sample 21). ASSESSMENT: This spreadsheet presents the standard deviation and relative standard deviation for the repeated samples QL.B1 and Sample 21. This allows assessment of the repeatability of the reading for each oxide. TRANSFORMED DATA: This spreadsheet presents the original dataset, the conversion of the trace elements from oxide (%) to trace (ppm), the normalisation of the data without sodium oxide and the scaling to 100%. FINAL DATASET: This spreadsheet presents the chosen variables and selected samples normalised and then logged to base 10. This data was generated using a Bruker S2 Ranger with internal calibration.

本数据集将在相关研究发表后完全开放获取。本数据集包含从马耳他宰敦别墅（Żejtun Villa）与塔西尔格圣所（Tas-Silġ Sanctuary）考古遗址出土的晚迦太基-早期罗马时期陶器残片所采集的能量色散X射线荧光（Energy Dispersive X-Ray Fluorescence, EDXRF）原始数据。本数据由Emma Richard-Trémeau、Joseph Grech与Alexandra Humann在马耳他大学John Charles Betts工程博士的指导下，作为“马耳他遗址陶器陶系特征汇编（Compiling Fabric Identity for Pottery from Maltese Sites, CoFIPoMS）”项目的一部分进行分析与处理。本数据集涵盖陶器残片与原材料（本地黏土样品）的检测读数，属于成分类数据集。本Zenodo存档包含以下内容：原始数据（压缩包）：所有待测样品的EDXRF原始检测数据，以氧化物百分比（%）形式呈现。共包含四张电子表格：黏土样品数据、陶器样品数据，以及一份黏土样品（QL.B1）与一份陶器样品（Sample 21）的重复检测读数。重复性评估表：该电子表格展示了QL.B1黏土样品与Sample 21陶器样品重复检测的标准差与相对标准差，可用于评估每种氧化物检测读数的重复性。转换后数据：该电子表格包含原始数据集、将痕量元素从氧化物百分比（%）转换为痕量浓度（ppm）、去除氧化钠后的数据归一化，以及将数据缩放至100%的处理结果。最终数据集：该电子表格包含经归一化后以10为底取对数的选定变量与筛选后样品数据。本数据通过配备内置校准模块的布鲁克S2 Ranger（Bruker S2 Ranger）仪器采集生成。更多信息可通过以下途径获取：-https://www.um.edu.mt/library/oar/handle/123456789/109715 -https://www.um.edu.mt/projects/cofipoms/ 或联系第一作者：https://www.researchgate.net/profile/Emma-Richard-Tremeau/research。本数据集采用知识共享署名4.0国际许可协议（Creative Commons Attribution 4.0 International）进行授权：只要对本存档的作者予以恰当署名，即可自由使用与分享本数据集。
