Bonnet Plume River Intrusions: Paleoproterozoic Arc Geochemistry Evidence

The Bonnet Plume River intrusions dataset provides geochemical and geological evidence for a 1.71 Ga volcanic arc in Yukon, Canada. The Government of Yukon published this analysis, which includes findings from 2009 field work and geochemical modeling. The data was last updated on April 17, 2026.

Use Cases

• Classify volcanic arc signatures based on trace element geochemistry
• Model crystal fractionation processes based on pyroxene, plagioclase, and olivine dominance
• Study rock alteration and metasomatism in preserved clasts
• Analyze the relationship between intrusive rocks and Wernecke breccias

Strengths

• Geochemical modeling demonstrates crystal fractionation dominated by pyroxenes, plagioclase, and olivine
• Trace element analysis reveals a mafic to intermediate, calc-alkaline volcanic arc signature
• Field work conducted in 2009 confirmed intrusion relationships

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Major oxides are described as of little use in classification
• Row count is unknown, which may limit suitability assessment
