Endeavour segment ISS (Integrated Study Site) basalt geochemical analyses

**This is a new version of a previously submitted dataset.** Excel spreadsheet of >300 major, trace, and isotope analyses of basalt lavas from the Endeavour segment of the Juan de Fuca Ridge. Most samples were collected by submersible and a location map on <1m resolution bathymetry is provided. Most samples are Holocene in age, and all analyses are normalized to common values. Basalts range in composition from highly depleted to highly enriched at short spatial and temporal scale.

本数据集为此前提交版本的更新版。该数据集包含胡安·德·富卡洋脊（Juan de Fuca Ridge）恩代弗尔段（Endeavour segment）玄武岩熔岩的300余项主量、微量及同位素分析数据的Excel电子表格。多数样品通过载人潜水器采集，同时附带分辨率优于1米的水深地形（bathymetry）位置图。多数样品形成于全新世（Holocene），所有分析数据均已归一化至通用参考值。该批次玄武岩的成分在较短的空间与时间尺度内，呈现出从极度亏损到极度富集的变化范围。
