LA-ICP-MS results for glass vessels from Unguja Ukuu in Zanzibar.

Results are presented in weight percent oxide/element and ppm/element. EPMA results for the major and some minor element oxides (Na2O, SiO2, CaO, MgO, K2O and Al2O3) and the LA-ICP-MS results for the minor and trace elements. (XLSX)分析结果以氧化物/元素的质量百分比以及元素的百万分比（ppm）形式呈现。其中，主量元素与部分次要元素氧化物（Na₂O、SiO₂、CaO、MgO、K₂O及Al₂O₃）的测试数据由电子探针显微分析（Electron Probe Microanalysis, EPMA）获得，次要及微量元素的测试数据则通过激光剥蚀-电感耦合等离子体质谱（Laser Ablation Inductively Coupled Plasma Mass Spectrometry, LA-ICP-MS）获取，所有数据以XLSX格式存储。
