Yukon Magnetic Geophysical Data Reprocessing for NTS 115I

Yukon, Canada, magnetic geophysical data from assessment reports submitted before March 2015 have been reprocessed. Aurora Geosciences Ltd. performed the review, leveling individual reports and integrating them with 1:250,000 scale compilations. The output includes four gridded PDF products: residual total magnetic field, reduced to pole, vertical derivative, and tilt derivative.

Use Cases

• Mineral exploration targeting based on processed magnetic field derivatives.
• Geological mapping and structural interpretation based on reduced-to-pole magnetic data.
• Integrating historical assessment data with regional compilations for a unified geophysical model.

Strengths

• Data integrated from multiple assessment reports into standardized 1:250,000 scale compilations.
• Includes four derivative data products (residual, reduced-to-pole, vertical derivative, tilt derivative) for enhanced analysis.
• Original source data is documented and available in a referenced open file (YGS Open File 2017-38).

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 may reflect temporal bias, as it includes only reports submitted prior to March 2015.
