A synthesis of pluton data records the transition from arc to syn-collisional and post-collisional magmatism in Yukon's Intermontane terranes. The dataset, hosted by the Government of Yukon on open_canada, supports a revised tectonic model involving slab rollback and lithospheric delamination. It was last updated on April 17, 2026.
Use Cases
- Modeling tectonic evolution based on Late Triassic to Jurassic pluton data
- Analyzing magmatic migration patterns based on the southward migration of syn-collisional magmatism
- Investigating crustal contributions to magmatism based on isotopic compositions and stratigraphic evidence
- Comparing regional tectonic styles based on contrasts between Yukon and coeval juvenile arc magmatism in British Columbia
Strengths
- Focuses on a specific tectonic transition period from Late Triassic to Jurassic
- Integrates data from multiple Intermontane terranes (Stikinia, Yukon-Tanana, Cache Creek)
- Last updated on April 17, 2026, indicating recent maintenance
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 Yukon region
