Jinshan Volcano Geochemical Data for Cenozoic Magmatic Processes in North China

Geochemical data from the Cenozoic Jinshan volcano in the Datong Volcanic Field provides insights into intraplate crustal magmatic processes. The dataset includes whole-rock major and trace element geochemistry, mineral geochemistry, and thermobarometer studies for alkaline basalts. It was authored by Wenqing Gao and last updated on June 3, 2026.

Use Cases

• Modeling magma ascent and stalling depths based on clinopyroxene thermobarometry data.
• Analyzing mantle source characteristics and lithospheric thinning using OIB-like geochemical signatures.
• Investigating redox conditions and crystallization temperatures from olivine composition data.
• Studying melt-mush interactions and polybaric crystallization in a multi-level crustal system.

Strengths

• Includes specific geochemical measurements, such as crystallization temperatures of 1179–1255°C and oxygen fugacity of QFM +0.6.
• Provides depth constraints for crystallization from clinopyroxene thermobarometers (3–9 km and 17–23 km).
• Released under a permissive CC-BY-4.0 license for open reuse.

Limitations

• Dataset is small at 557.5 KB, indicating limited scope and likely a focused case study.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical analysis.
