Deadman Pluton Paleomagnetism: Post-Mid-Cretaceous Tectonic Motion in Yukon

237 paleomagnetic specimens from 23 sites within the ~91 Ma Deadman pluton in central Yukon. The data includes characteristic remanent magnetization directions and paleopole calculations, produced by the Government of Yukon. The dataset was last updated in April 2026.

Use Cases

• Calculate paleomagnetic poles based on declination and inclination data from 23 sites.
• Analyze post-emplacement tectonic displacement based on discordance with the North American cratonic paleopole.
• Model the structural deformation of the Dawson thrust sheet using paleomagnetic evidence.
• Study the relationship between pluton crystallization and magnetic remanence in alkalic intrusions.

Strengths

• 237 paleomagnetic specimens provide a substantial sample size.
• 23 distinct sampling sites across three plutonic phases, dykes, and contact zones.
• Mean paleomagnetic direction and paleopole are calculated with statistical parameters (e.g., α95 = 2.6°, k = 139).

Limitations

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