Paleomagnetic Conglomerate Tests from the Whitehorse Trough, Yukon

Paleomagnetic conglomerate tests were conducted at three localities in the Jurassic Laberge Group of the southern Yukon. The Government of Yukon collected 120 cores from 32 clasts and 8 matrix samples, yielding 190 specimens analyzed using standard demagnetization techniques. The dataset was last updated on April 17, 2026.

Use Cases

• Testing for remagnetization events based on characteristic remanent magnetization (ChRM) directions
• Analyzing hydrothermal fluid flow impacts during the Laramide Orogeny based on matrix remagnetization
• Validating primary ChRM directions in felsic plutons based on clast data
• Correlating paleomagnetic data with specific plutonic bodies like the Mount Lorne stock or Whitehorse batholith

Strengths

• Data includes 190 paleomagnetic specimens derived from 120 cores
• Tests were conducted at three distinct localities spaced 5, 20, and 40 km from a geological margin
• Analysis distinguishes between clast and matrix (greywacke) compositions and their respective ChRM carriers

Limitations

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