Yukon Magnetic Geophysical Data Reprocessing for NTS 105F

Aurora Geosciences Ltd reprocessed publicly available magnetic data from assessment reports submitted before March 2015. The data were levelled and integrated with 1:250,000 scale compilations to produce four standardized gridded products. This work was contracted by the Government of Yukon and the original data is referenced in YGS Open File 2017-14.

Use Cases

• Map subsurface geological structures based on the reprocessed residual total magnetic field grid.
• Enhance magnetic anomaly interpretation for mineral exploration using the reduced-to-pole grid.
• Identify near-surface magnetic features based on the vertical derivative grid.
• Analyze magnetic source edges and boundaries based on the tilt derivative grid.

Strengths

• Data integration includes assessment reports submitted prior to March 2015, providing a defined temporal scope.
• Four distinct processed magnetic grids (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative) offer multiple analytical layers.
• Data is levelled and standardized against 1:250,000 scale compilations, suggesting consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Yukon's NTS 105F region.
