New electron microprobe analyses characterize hydrothermal and plutonic regimes in the Keno Hill district. Staurolite-garnet-albite-biotite schist records contact metamorphic conditions averaging 518°C and 3450 bar. Hydrothermal veins indicate conditions of approximately 400°C and 1500 bar, with both systems interpreted to be emplaced near 10-13 km depth.
Use Cases
- Modeling contact metamorphic conditions based on mineral assemblages like staurolite-garnet-albite-biotite
- Estimating hydrothermal vein emplacement depth based on pressure-temperature data
- Comparing lithostatic and hydrostatic regimes for plutonic and vein systems
Strengths
- Includes specific pressure and temperature measurements (e.g., 518°C, 3450 bar)
- Provides depth estimates for two geological systems (10-13 km)
- Based on new electron microprobe analyses of field-collected samples
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
Provenance
