Yukon Magnetic Geophysical Data Reprocessed for NTS 115G

Aurora Geosciences Ltd reprocessed 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 PDF products. The original 250k geophysical data is available in YGS Open File 2017-36.

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 detection based on residual total magnetic field and reduced-to-pole grids.

Strengths

• Data integrated from multiple assessment reports into standardized 1:250,000 scale compilations.
• Four derivative products (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative) provide multiple analytical views.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the Yukon assessment report system.
• Row count and specific data volume are unknown, which may limit suitability assessment.
