Data for Calcium isotopic compositions of eclogite melts and negligible modification during reaction with lithospheric mantle

This dataset includes (1) Chemical and isotopic compositions of the potassic basalts from northeast China in this study (Table S1) and standards (Tables S2-3); (2) Melting of MORB-like eclogite and peridotite with evolving modal composition in melting residue (Tables S4-5); and (3) Modelling the reaction between initial melts and lithospheric mantle (Table S6).

本数据集涵盖以下三部分内容：(1) 本研究测定的中国东北部钾质玄武岩（potassic basalts）的化学与同位素组成数据（表S1）及标准样品分析数据（表S2~S3）；(2) 熔融残余体模态组成发生演化的类洋中脊玄武岩（MORB-like）榴辉岩（eclogite）与橄榄岩（peridotite）的熔融实验数据（表S4~S5）；(3) 初始熔体与岩石圈地幔（lithospheric mantle）间反应过程的模拟数据（表S6）
