MORB geochemistry from the Central Indian Ridge segments between 12°S and 17°S.

This dataset presents new geochemical (major oxide, trace element, and Sr-Nd-Pb isotopic) of MORB glasses from the Central Indian Ridge segments between 12°S and 17°S. A series of submarine pillow basalts were collected by dredging during the expedition by R/V ISABU in 2019 along the CIR (between 14°S and 17°S). In addition to these nine new samples, twenty-four samples of fresh basaltic glasses from segments between 12°S and 16°S (from previous cruises of the R/V Onnuri, part of the KODOS program), which part of them have not been analyzed for Sr, Nd, and Pb, were selected for further analysis.

本数据集展示了来自中印度洋脊（12°S至17°S之间）段落的MORB（镁铁质橄榄岩）玻璃的新地质化学数据，包括主要氧化物、微量元素以及Sr-Nd-Pb同位素。2019年，R/V ISABU科考船在CIR（12°S至17°S之间）沿线进行探险时，通过疏浚作业收集了一系列海底枕状玄武岩。除了这九个新样本外，还选择了二十四份来自12°S至16°S段落（源自R/V Onnuri的先前航次，作为KODOS计划的一部分）的全新玄武岩玻璃样本，其中部分样本尚未进行Sr、Nd和Pb的分析，以供进一步分析。
