MORB geochemistry from the Central Indian Ridge segments between 8°S and 12°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 8°S and 12°S. A series of submarine pillow basalts were collected by dredging by R/V Onnuri during three expeditions operated in 2009, 2011 and 2017 (part of the KODOS program - KODOS09-11 and CIR1701 expeditions).

本数据集收录了南纬8°至12°区间内中印度洋海岭区段产出的洋中脊玄武岩（Mid-Ocean Ridge Basalt，MORB）玻璃的全新地球化学数据，涵盖主量氧化物、微量元素及Sr-Nd-Pb同位素组成。研究团队借助Onnuri号科考调查船（R/V Onnuri），在2009年、2011年与2017年开展的三次科考航次（隶属于KODOS计划，对应航次为KODOS09-11与CIR1701）中，通过拖网采样获取了一系列海底枕状玄武岩样品。
