Sm-Nd Isotope Data Compilation from Geoscientific Literature

Derived from tables within geoscientific literature, we utilized our advanced automated tabular data collection tool to extract data from 3,959 geoscientific articles specifically focusing on Sm-Nd isotopes, out of an extensive repository of over 20,000 geoscientific publications. All the samples referenced are igneous rocks, and the data originates from peer-reviewed sources. To streamline the data extraction process, a team of experts curated a list of 25 pertinent keywords, encompassing terms such as Sm, 143 Nd/144 Nd, and Pluton/Formation. The file titled "Sm-Nd data collection (automated).xls" encapsulates the outcomes of the automated extraction, while "Sm-Nd data collection (annotation).xls" documents human annotations for 2,118 selected entries from the automated dataset, subjected to meticulous human evaluation. Other files are our previously construed Sm-Nd isotope dataset under repository of https://doi.org/10. 6084/m9.figshare.22345072.v1.

本数据集源自地球科学文献中的表格内容：我们依托自研的先进自动化表格数据采集工具，从包含2万余篇文献的大型地球科学文献库中，筛选出3959篇聚焦钐-钕（Sm-Nd）同位素的相关文章并提取其中数据。所有涉及的样品均为火成岩，数据均来自经同行评议的文献来源。为优化数据提取流程，专家团队精选并整理了25个相关关键词，涵盖Sm、¹⁴³Nd/¹⁴⁴Nd以及深成岩体/地层等术语。命名为"Sm-Nd data collection (automated).xls"的文件收录了自动化提取的全部结果；而"Sm-Nd data collection (annotation).xls"则记录了从自动化数据集中筛选出的2118条条目的人工标注内容，该部分经过了细致的人工评估校验。其余文件为本团队此前构建的钐-钕同位素数据集，存储于https://doi.org/10.6084/m9.figshare.22345072.v1。
