Quartet Mountain Lamprophyre Suite Geology in Yukon

The Quartet Mountain lamprophyre suite comprises Early Cambrian volatile-rich ultramafic alkaline dikes in the Wernecke Mountains of northern Yukon. The dataset likely contains geological descriptions and analyses of these rocks, including their mineralogy and potential diamond hosting. It was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Classifying ultramafic lamprophyre types based on described mineralogy of phlogopite, diopside, and olivine
• Assessing diamond potential in alkaline igneous rocks based on the described kimberlitic affinity
• Modeling mantle melting depths (>90 km) and tectonic settings for Early Paleozoic extension
• Comparing lamprophyre compositions with kimberlite based on described xenolith and xenocryst content

Strengths

• Description provides specific mineralogical details including phenocrysts of phlogopite ± diopside ± olivine
• Includes a specific geological age context (Early Cambrian) and tectonic interpretation (Early Paleozoic extension)
• Last updated date is explicitly provided (2026-04-17)

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 the specific Wernecke Mountains location
