中国东部玄武岩的Mg和Zn同位素数据

本数据集主要包括对中国东部玄武岩样品的Mg和Zn同位素分析结果，样品采样地点包括南京、绍兴、宁德、三名、漳州等地区，样品为晚中生代到新生代玄武岩。主要包括全岩主/微量元素、Sr-Nd-Mg-Zn同位素分析。使用的仪器包括XRF、ICP-MS、MC-ICPMS。主量元素由XRF获取，样品酸消解并通过离子交换树脂分离后，随后用MC-ICPMS测试锶、钕、镁和锌同位素，测试时选择国际通用的标准样品对测试数据进行监控，测试于2018-01-31 至 2020-05-31期间完成。获得的数据对幔源岩浆岩的Mg-Zn同位素组成提供重要信息。This dataset primarily contains Mg and Zn isotopic analysis results for basalt samples from eastern China. The sampling locations include Nanjing, Shaoxing, Ningde, Sanming, Zhangzhou and other areas, and the samples are Late Mesozoic to Cenozoic basalts. The dataset covers whole-rock major and trace element analyses as well as Sr-Nd-Mg-Zn isotopic analyses. The instruments used are XRF, ICP-MS and MC-ICPMS. Major elements were determined by XRF. After acid digestion and separation with ion-exchange resins, Sr, Nd, Mg and Zn isotopes were measured using MC-ICPMS. Internationally certified reference materials were adopted to monitor the analytical data during the testing period. The analytical work was conducted from January 31, 2018 to May 31, 2020. The obtained data provide critical constraints on the Mg-Zn isotopic compositions of mantle-derived magmatic rocks.
