Yushishan and Yueyashan Ophiolite Geochemical and Geochronological Data

Lei Wu presents zircon U-Pb geochronology and whole-rock geochemical data for the Yushishan and Yueyashan ophiolites in the Beishan orogenic belt, China. The dataset includes compositional data for serpentinized peridotite, olivine pyroxenite, cumulate gabbro, basalt, and plagiogranite, with zircon ages indicating formation around 535.0 and 539.0 Ma. It was published on figshare under a CC-BY-4.0 license and last updated on 2026-06-04.

Use Cases

• Modeling petrogenesis of ophiolites based on whole-rock geochemical data.
• Constraining tectonic settings based on trace element patterns like HFSE depletion and LILE enrichment.
• Dating geological events and ocean-continent transitions based on zircon U-Pb ages.
• Correlating ophiolite belts based on geochemical and geochronological similarities.

Strengths

• Specific geochemical data points are provided, such as TiO2 content ranges for gabbros and basalts.
• Zircon U-Pb ages are given with precision to the specific formation period (early Cambrian, ~535-539 Ma).
• The dataset focuses on a well-preserved and significant ophiolite belt, the Hongliuhe-Baiyunshan Ophiolite Belt.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small in size (678.1 KB), indicating limited scope.
