Yukon Magnetic Geophysical Data Reprocessing for NTS 115A

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 scale compilations to produce four standardized gridded products. The original 250k geophysical data is available in YGS Open File 2017-32.

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 into regional compilations based on the 1:250,000 scale.
• Analyzing subsurface magnetic anomalies based on vertical and tilt derivative grids.

Strengths

• Data integrated from multiple assessment reports into standardized 1:250,000 scale compilations.
• Includes four processed derivative products (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative).
• Original source data is documented in a specific open file (YGS Open File 2017-32).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the source, as it includes reports submitted only prior to March 2015.
