Crystallization Depth Estimates for Yukon Batholiths

Pressure estimates of 6.4-7.2 kbar for the Tatchun batholith and 3.4-4.2 kbar for the Aishihik batholith were calculated using the aluminum-in-hornblende geothermobarometer. The dataset, published by the Government of Yukon, contains results from applying this method to Early Jurassic plutons in west-central Yukon. It was last updated on April 17, 2026.

Use Cases

• Estimate crustal emplacement depths based on aluminum-in-hornblende geothermobarometry results
• Model exhumation rates based on crystallization depths and geochronological data mentioned in the description
• Assess mineral prospectivity for copper deposits based on inferred crustal levels and batholith characteristics

Strengths

• Provides specific pressure ranges (6.4-7.2 kbar and 3.4-4.2 kbar) and depth estimates (23-26 km and 12-15 km)
• Includes calculated exhumation rate estimates (~1.2-2.0 mm/a)
• Data originates from the authoritative Government of Yukon

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
