LA-ICP-MS analyses of 60 elements in 319 MORB glasses

LA-ICP-MS analyses of 60 elements in 319 MORB glasses from Mid-Atlantic Ridge and Mid-Cayman Rise, along with the mass peaks, isobaric interference corrections, external standards and detection limits of measured elements. Duplicate analyses of VG 2 and USGS glasses that are used to assess the long-term analytical precision are also included in this dataset, with the measurement and the analytical uncertainty of VG 2 from Jenner and O’Neill (2012), the measurements and the uncertainties of Tl contents of USGS glasses from Nielsen and Lee (2013), and the GeoReM values of USGS glasses for comparisons.本数据集包含来自大西洋中脊（Mid-Atlantic Ridge）与开曼海岭中部（Mid-Cayman Rise）的319件大洋中脊玄武岩（MORB, Mid-Ocean Ridge Basalt）玻璃的60种元素的激光剥蚀-电感耦合等离子体质谱法（LA-ICP-MS, Laser Ablation Inductively Coupled Plasma Mass Spectrometry）分析数据，同时涵盖待测元素的质谱峰、同量异位素干扰校正方案、外标样以及检出限信息。此外，本数据集还纳入了用于评估长期分析精度的VG 2标样与美国地质调查局（USGS, United States Geological Survey）玻璃标样的重复分析结果：其中VG 2标样的测量值与分析不确定度取自Jenner与O’Neill（2012）的研究，USGS玻璃标样中铊（Tl）含量的测量值及不确定度取自Nielsen与Lee（2013）的研究，同时附带USGS玻璃标样的GeoReM（Geochemical Reference Database）参考值用于对比分析。
