俯冲带碳酸盐循环的Mg、Zn同位素示踪数据

数据内容：汇总了俯冲带碳酸盐循环过程中的钾质岩浆和煌斑岩、板内碱性玄武岩、苦橄岩的Mg、Zn同位素变化范围（见参考文献），在此基础上提出俯冲带碳酸盐岩混合模型图（数据图和模拟图），并提供了碳酸盐岩和地幔混合模型的参数表。数据来源：中国地质大学（北京）同位素实验室。加工方式：将符合要求的数据从公开发表的文献中采集。数据质量：所有数据经过检查，确保数据可靠且可以体现科学问题后汇总成图；数据中的表格为碳酸盐岩和地幔混合模型的参数表。数据应用：展示碳酸盐在俯冲带中的过程（按不同深度可分为三种循环过程）以及不同俯冲过程产生的幔源岩石的的镁、锌同位素组成大致范围。数据可为判定岩石样品来源深度和碳酸盐俯冲过程提供依据。Data Content: This dataset summarizes the ranges of Mg and Zn isotopic compositions of potassic magmas, lamprophyres, intraplate alkaline basalts, and picrites related to carbonate cycling in subduction zones (see references cited). Based on these data, mixed model diagrams of subduction zone carbonates (including data plots and simulation figures) are proposed, and parameter tables for carbonate-mantle mixing models are provided. Data Source: Isotope Laboratory, China University of Geosciences (Beijing). Data Processing: Qualified data were collected from peer-reviewed published literature. Data Quality: All data were inspected to ensure their reliability and scientific significance before being compiled into plots; the tables included in the dataset are the parameter tables for carbonate-mantle mixing models. Data Applications: This dataset illustrates the carbonate cycling processes in subduction zones, which are divided into three cyclic stages based on varying depths, as well as the approximate ranges of Mg and Zn isotopic compositions of mantle-derived rocks generated by different subduction processes. It can provide evidence for constraining the source depth of rock samples and reconstructing carbonate subduction processes.
