Geochemistry of ODP Leg 129 igneous rocks

This report presents all the available major and trace elemental analyses and Sr, Nd, and Pb isotopic compositions of basaltic rocks recovered from Ocean Drilling Program Sites 800, 801, and 802 during Leg 129 (Table 1). Its main purpose is to provide other investigators a complete summary of geochemical data for Leg 129 basement basalts that they can use for later work. Detailed discussions of the data are presented elsewhere in the volume by Floyd and Castillo (Site 801 geochemistry and petrogenesis, dataset: doi:10.1594/PANGAEA.779154) Floyd et al. (Sites 800 and 802 geochemistry and petrography, dataset: doi:10.1594/PANGAEA.779129), Alt et al. (Site 801 alteration, dataset: doi:10.1594/PANGAEA.779207), and Castillo et al. (Sr, Nd, and Pb isotope geochemistry of Leg 129 basalts, dataset: doi:10.1594/PANGAEA.779191).

本报告收录了大洋钻探计划（Ocean Drilling Program, ODP）第129航次期间采自800、801及802站位的玄武岩的全部可获取主量元素、微量元素分析数据，以及Sr、Nd、Pb同位素组成，详情见表1。本报告的核心宗旨是为其他科研人员提供一套完整的第129航次基底玄武岩地球化学数据汇总，以供其开展后续研究使用。针对该数据集的详细论述已刊载于本卷的其他章节，具体包括Floyd与Castillo（801站位地球化学与岩石成因，数据集DOI：10.1594/PANGAEA.779154）、Floyd等人（800与802站位地球化学及岩相学，数据集DOI：10.1594/PANGAEA.779129）、Alt等人（801站位蚀变作用，数据集DOI：10.1594/PANGAEA.779207）以及Castillo等人（第129航次玄武岩Sr、Nd、Pb同位素地球化学，数据集DOI：10.1594/PANGAEA.779191）。
