Yukon Magnetic Geophysical Data Reprocessing for NTS 115O

Yukon magnetic geophysical data from assessment reports submitted prior to March 2015 were reviewed and processed by Aurora Geosciences Ltd. The data were levelled and integrated with 1:250,000 scale compilations to produce standardized products. Four gridded PDF maps were generated, including residual total magnetic field, reduced to pole, vertical derivative, and tilt derivative.

Use Cases

• Mineral exploration targeting based on processed magnetic field derivatives.
• Regional geological mapping based on integrated 1:250,000 scale magnetic compilations.
• Geophysical anomaly interpretation based on the reduced-to-pole and tilt derivative grids.

Strengths

• Data integrated from multiple assessment reports into standardized 1:250,000 scale compilations.
• Includes four distinct processed magnetic field products (residual, reduced to pole, vertical derivative, tilt derivative).
• Original source data is documented in a specific open file (YGS Open File 2017-42).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data freshness should be verified as the underlying assessment reports are from before March 2015.
