Yushishan and Yueyashan Ophiolite Geochemistry and Geochronology Data

The dataset provides zircon U-Pb geochronology and whole-rock geochemical data from the Yushishan and Yueyashan ophiolites in the Beishan orogenic belt, China. It was authored by Lei Wu and published on figshare under a CC-BY-4.0 license. The data constrains the formation of the Hongliuhe-Baiyunshan Ophiolite Belt to the early Cambrian period.

Use Cases

• Constraining tectonic settings based on whole-rock geochemical signatures like TiO2 content and REE patterns.
• Dating ophiolite formation events using zircon U-Pb geochronology data.
• Modeling the petrogenesis of ophiolitic rocks from geochemical data of serpentinized peridotite, gabbro, and basalt.
• Investigating subduction zone processes based on trace element patterns (e.g., HFSE depletion, LILE enrichment).

Strengths

• Data includes specific geochemical measurements, such as TiO2 weight percentages for gabbros and basalts.
• Zircon U-Pb ages provide precise temporal constraints for ophiolite formation, cited as approximately 535.0 Ma and 539.0 Ma.

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 (687.1 KB), indicating a limited scope.
