Cenozoic Faulting Thermochronology Data from Upper Hyland River Valley, Yukon

The Government of Yukon presents new low-temperature thermochronology data and thermal history models from the Upper Hyland River Valley area in southeastern Yukon. The data documents accelerated cooling between ca. 60–50 Ma and proposes ∼4–5.5 km of local exhumation driven by fault activation. The dataset was last updated on April 17, 2026.

Use Cases

• Modeling thermal histories based on low-temperature thermochronology data.
• Analyzing fault displacement timing and magnitude based on localized cooling evidence.
• Investigating relationships between regional fault networks based on oblique strike connections.
• Estimating exhumation magnitudes based on proposed ∼4–5.5 km of local displacement.

Strengths

• Thermochronology data documents a specific accelerated cooling period between ca. 60–50 Ma.
• Proposes a quantified estimate of ∼4–5.5 km of local exhumation.
• Links faulting activity to a major lithospheric-scale structure, the Tintina fault, thought to have accommodated ∼430 km of strike-slip.

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 Upper Hyland River Valley study area.
