Data tables of mineral and bulk-rock chemistry for rocks from Aitutaki and Rarotonga Islands, Cook Islands

Presented data include mineral compositions of a lherzolite xenolith (named AI70) with bulk major-element compositions and Sr-Nd-Pb isotope compositions of alkali basalts from Aitutaki and Rarotonga Islands, Cook Islands. The data provide an outlook for mantle heterogeneity in terms of mineral chemistry and Sr-Nd-Pb isotope geochemistry. Analytical methods are provided herein.

所提供的数据包括来自库克群岛的艾图塔基岛和拉罗汤加岛的碱性玄武岩（命名为AI70）的辉石岩异离体（Lherzolite Xenolith）的矿物组成，以及其全岩主量元素组成和Sr-Nd-Pb同位素组成。这些数据为研究地幔在矿物化学和Sr-Nd-Pb同位素地球化学方面的异质性提供了展望。本文档中提供了相应的分析方法。
