Mg-Zn isotopes in Mangaia HIMU lavas as tracers for ancient recycled carbonate

This dataset presents high-precision Mg (δ²⁶Mg) and Zn (δ⁶⁶Zn) isotopic analyses for a suite of HIMU-type lavas from Mangaia Island (Cook Islands, South Pacific).本数据集针对南太平洋库克群岛曼盖亚岛产出的一系列HIMU型熔岩（HIMU-type lavas），提供了高精度的镁（δ²⁶Mg）与锌（δ⁶⁶Zn）同位素分析结果。
