Mantle pyroxenites transformed from decarbonated altered oceanic crust controls the low-δ26Mg central-eastern Asian diffuse basaltic province

This dataset includes 1) Major, trace-element and Sr-Nd-Pb-Mg isotope data for Langshan basalts and lamprophyres, 2) Compilation of major, trace-element and Mg isotope data for the post-110 Ma intraplate basaltic magmatic province in central-eastern Asia, 3) Compiled experimental melt compositions from carbonated and uncarbonated rocks, 4) Details for the partial melting modeling of this study, and 5) Modelled δ26Mg and pyroxenitic mass contributions for adiabatic melts from mantle sources containing variable fractions of silica-deficient pyroxenite

本数据集涵盖如下内容：1) 狼山玄武岩与煌斑岩的主量元素、微量元素及Sr-Nd-Pb-Mg同位素数据；2) 东亚中东部地区110 Ma以来板内玄武岩岩浆省的主量元素、微量元素与Mg同位素数据汇编；3) 含碳酸盐及不含碳酸盐岩石的实验熔体成分汇编；4) 本研究的部分熔融模拟细节；5) 针对含不同比例贫硅辉石岩的地幔源区绝热熔体，模拟得到的δ²⁶Mg值与辉石岩质量占比。
