Jurassic-Cretaceous Granite Geochemistry and Zircon Data from Southern Great Xing'an Range

Zircon U-Pb ages from 182 to 125 million years ago constrain three distinct magmatic pulses in the southern Great Xing'an Range. The dataset combines new and published geochemical and Hf isotopic measurements to investigate granite petrogenesis. Researcher Peng Wang compiled this data, last updated in April 2026.

Use Cases

• Classify granite types (I-type) using whole-rock geochemistry columns like LREE, HREE, LILE, and HFSE concentrations.
• Model crustal source ages and mantle contributions using zircon εHf(t) values and U-Pb age columns.
• Correlate magmatic pulses (182-164 Ma, 162-146 Ma, 144-125 Ma) with tectonic events using the classified age data.
• Identify geochemical signatures of extensional vs. compressional settings using trace element anomaly columns for Nb, Ti, and Eu.

Strengths

• Data spans a 57-million-year period from the Middle Jurassic to Early Cretaceous (182-125 Ma).
• Integrates newly obtained measurements with previously published data for broader context.
• Includes multiple analytical methods: zircon U-Pb dating, Hf isotopic analysis, and whole-rock geochemistry.

Limitations

• Small dataset at 2.0 MB, suggesting a limited number of individual rock samples or data points.
• Spatial coverage is restricted to the southern Great Xing'an Range in Northeast China.
• Sample data and specific row/column counts are unavailable, obscuring the dataset's exact scale.
