Yukon Magnetic Geophysical Data Reprocessing for NTS 106B

Aurora Geosciences Ltd reprocessed publicly available digital magnetic geophysical data submitted with assessment reports to the Government of Yukon. The work integrated individual assessment report data with 1:250,000 compilations and produced four gridded PDFs. Data submitted prior to March 2015 were considered.

Use Cases

• Geological mapping based on processed magnetic field grids.
• Mineral exploration targeting based on derivative magnetic products.
• Integrating historical assessment data into regional compilations.
• Analyzing subsurface structures based on reduced-to-pole magnetic data.

Strengths

• Data was levelled and integrated with regional 1:250,000 compilations.
• Four standardized derivative products (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative) were produced.
• Original source data is referenced to a specific open file (YGS Open File 2017-25).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias inherent to open_canada, as only data submitted before March 2015 was considered.
• Row count is unknown, which may limit suitability assessment.
