高精度低Mo含量火成岩样品Mo同位素MC-ICP-MS分析数据集

本文数据包含不同类型火成岩标样（玄武岩BIR-1a, 辉绿岩W-2a, 纯橄岩DTS-2b、WPR-1和橄榄岩GPt-3）和低Mo含量淡色花岗岩Mo含量和同位素比值分析数据。淡色花岗岩采自西藏南部萨嘎、错那和正嘎地区；Mo同位素分析数据通过使用多收集器-电感耦合等离子体质谱（MC–ICP–MS）测定，获得的标样及淡色花岗岩数据用与验证所建立的低Mo含量样品分析方法的精度和准确度，以实现对更多的低含量样品进行高精度的Mo同位素分析。

This dataset includes analytical data of Mo concentrations and isotopic ratios for two categories of samples: 1) various igneous rock reference materials (basalt BIR-1a, diabase W-2a, dunite DTS-2b, WPR-1, and peridotite GPt-3), and 2) low-Mo leucogranites. The leucogranites were sampled from Saga, Cona, and Zhengga regions in southern Tibet. The Mo isotopic data were measured via multi-collector inductively coupled plasma mass spectrometry (MC–ICP–MS). The data obtained from both the reference materials and the leucogranites were utilized to verify the precision and accuracy of the newly established analytical method for low-Mo content samples, thereby facilitating high-precision Mo isotopic analysis of more such low-concentration samples.
