Reprocessing of Yukon Magnetic Data for NTS 115B

Aurora Geosciences Ltd performed a review of publicly available digital magnetic geophysical data submitted with assessment reports to develop standardized products and compilations. Data submitted prior to March 2015 were considered, levelled, and integrated with 1:250,000 compilations. Four gridded PDFs have been produced, and original data can be found in YGS Open File 2017-33.

Use Cases

• Analyze subsurface geological structures based on the residual total magnetic field data.
• Interpret magnetic anomalies for mineral exploration based on the reduced-to-pole data.
• Enhance edge detection of geological features based on the vertical derivative data.
• Map subtle magnetic gradients based on the tilt derivative data.

Strengths

• Data were levelled and integrated with 1:250,000 compilations, suggesting a standardized product.
• Four derivative products (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative) are provided.
• Original data is referenced to a specific open file (YGS Open File 2017-33).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
