The Mount Harper Volcanic Complex dataset describes a middle Neoproterozoic (717 Ma) calc-alkaline magmatic suite from the Ogilvie Mountains. The Government of Yukon provides geochemical data on low Al2O3, Na2O, and TiO2 contents, suggesting a picritic melt from a harzburgitic source. The data was last updated on 2026-04-17.
Use Cases
- Model mantle potential temperatures based on described geochemical trends.
- Compare rift system magmatism with other Franklin Igneous Province occurrences.
- Analyze crustal attenuation constraints based on mantle melting depth (~6 km).
- Study harzburgitic source rock compositions from low oxide content data.
- Investigate partial melt products at dispersed mantle plume margins.
Strengths
- Geochemical data includes specific oxide content measurements (Al2O3, Na2O, TiO2).
- Dataset provides a precise geological age (717 Ma).
- Analysis includes a constraint on mantle melting depth (~6 km).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to open_canada.
