Yukon Magnetic Geophysical Data Reprocessing for NTS 105D

Aurora Geosciences Ltd reprocessed publicly available digital magnetic geophysical data from assessment reports submitted prior to March 2015. The data were levelled and integrated with 1:250,000 compilations to produce four standardized gridded products. The dataset is provided by the Government of Yukon and was last updated in May 2026.

Use Cases

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

Strengths

• Data processed and levelled to a standardized 1:250,000 scale.
• Includes four derivative products (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative).
• Original source data is documented in YGS Open File 2017-12.

Limitations

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