Nd isotope data for Réunion Island basalts and cumulate xenoliths

This dataset contains neodymium isotope data for intraplate basalts and cumulates from Piton des Neiges and Piton de la Fournaise, La Réunion (FR). It lists dynamically-corrected 142Nd/144Nd values, which were the focus of the study, dynamically-corrected 143Nd/144Nd, 145Nd/144Nd and 148Nd/144Nd values, and static 150Nd/144Nd, 140Ce/144Nd and 141Pr/144Nd values. Replicate measurements of JNdi, the terrestrial standard, are included for normalization of data from each analytical session. All data were collected on the ThermoScientific Triton thermal ionization mass spectrometer housed at the Department of Terrestrial Magnetism, Carnegie Institution for Science, Washington, DC, USA. The purpose of the study was to determine whether, at high-precision, isotopic variability driven by Hadean geological processes is detectible in young lavas.

本数据集包含留尼旺岛（法国，FR）内日峰（Piton des Neiges）与富尔奈斯火山（Piton de la Fournaise）产出的板内玄武岩（intraplate basalts）及堆晶岩（cumulates）的钕同位素（neodymium isotope）数据。数据集列出了本研究核心关注的经动态校正的¹⁴²Nd/¹⁴⁴Nd比值，以及经动态校正的¹⁴³Nd/¹⁴⁴Nd、¹⁴⁵Nd/¹⁴⁴Nd与¹⁴⁸Nd/¹⁴⁴Nd比值，同时包含经静态校正的¹⁵⁰Nd/¹⁴⁴Nd、¹⁴⁰Ce/¹⁴⁴Nd及¹⁴¹Pr/¹⁴⁴Nd比值。本数据集纳入了国际通用钕同位素标准物质JNdi的重复测量数据，用于每一轮分析批次的数据归一化处理。所有测试数据均采集自美国华盛顿特区卡内基科学研究所（Carnegie Institution for Science）地球地磁部（Department of Terrestrial Magnetism）的赛默飞世尔Triton型热电离质谱仪（ThermoScientific Triton thermal ionization mass spectrometer）。本研究的核心目标为：在高精度测试条件下，能否在年轻火山岩中识别出由冥古代（Hadean）地质作用所引发的同位素分异特征。
