摘要

自从出现了碎屑地质年代学以来,沉积物来源研究取得了重大进展。碎屑锆石 U-Pb 年龄谱,尤其是与锆石 Hf 同位素结合使用时,为确定沉积物的产地位置、性质和演化历史提供了强有力的工具。位于中国中部的西秦岭-松潘构造交界处是一个巨大的地壳结构。在松潘-甘孜和西秦岭地块的281个砂岩样本中,共获得了20640个锆石U-Pb年龄。其中,33 个样品的 1636 个锆石含有 Hf 同位素数据。此外,我们还整理了论文、样品、分析方法和结果等数据,共获得 76 个锆石 U-Pb 和 60 个 Hf 同位素数据头。所获得的数据集具有多个数据接口,可以很好地与不同领域的研究或应用相关联,如出处分析、气候变化和古地理重建研究等。

A database of detrital zircon U–Pb geochronology and Hf isotopes from the Songpan–Ganzi and Western Qinling terranes

Since the advent of detrital geochronology, significant progress has been made in the study of sedimentary sources. The detrital zircon U–Pb age spectrum, especially when combined with zircon Hf isotopes, provides a powerful tool for determining the provenance location, nature, and evolutionary history of sediments. The Western Qinling–Songpan tectonic junction, located in central China, is a giant structure on the crustal scale. A total of 20,640 zircon U–Pb ages of 281 sandstone samples from the Songpan–Ganzi and Western Qinling terranes were obtained. Among these, 1,636 zircons from 33 samples contained Hf isotopic data. Moreover, we compiled data on papers, samples, analytical methods, and results and obtained a total of 76 zircon U–Pb and 60 Hf isotope data heads. The obtained dataset has multiple data interfaces, which can be well associated with research or applications in different fields, for provenance analysis, climate change, and paleogeographic reconstruction studies.

期刊介绍: Geoscience Data Journal provides an Open Access platform where scientific data can be formally published, in a way that includes scientific peer-review. Thus the dataset creator attains full credit for their efforts, while also improving the scientific record, providing version control for the community and allowing major datasets to be fully described, cited and discovered. An online-only journal, GDJ publishes short data papers cross-linked to – and citing – datasets that have been deposited in approved data centres and awarded DOIs. The journal will also accept articles on data services, and articles which support and inform data publishing best practices. Data is at the heart of science and scientific endeavour. The curation of data and the science associated with it is as important as ever in our understanding of the changing earth system and thereby enabling us to make future predictions. Geoscience Data Journal is working with recognised Data Centres across the globe to develop the future strategy for data publication, the recognition of the value of data and the communication and exploitation of data to the wider science and stakeholder communities.
