Yukon Magnetic Geophysical Grids for NTS 115P

Aurora Geosciences Ltd processed publicly available digital magnetic geophysical data submitted with assessment reports prior to March 2015. The data were levelled and integrated with 1:250,000 compilations to produce four standardized gridded products. The original 250k geophysical data is available in YGS Open File 2017-43.

Use Cases

• Map subsurface geological structures based on the residual total magnetic field grid.
• Interpret magnetic sources based on the reduced-to-pole transformation grid.
• Enhance near-surface feature detection based on the vertical derivative grid.
• Analyze magnetic source geometry based on the tilt derivative grid.

Strengths

• Data integrated from multiple assessment reports into standardized compilations.
• Four derivative products (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative) provide multiple analytical perspectives.
• Original source data is documented in YGS Open File 2017-43.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the underlying assessment reports were submitted prior to March 2015.
• Row count is unknown, which may limit suitability assessment.
