Yukon Magnetic Geophysical Data Reprocessing for NTS 105O

Aurora Geosciences Ltd reprocessed publicly available digital magnetic geophysical data submitted with assessment reports to develop standardized products. Data submitted prior to March 2015 were levelled and integrated with 1:250,000 compilations. Four gridded PDFs have been produced, including residual total magnetic field and derivative maps.

Use Cases

• Analyze subsurface geological structures based on the reduced-to-pole magnetic field maps.
• Identify magnetic anomalies for mineral exploration based on the vertical derivative maps.
• Interpret geological boundaries and lithological contacts based on the tilt derivative maps.
• Integrate historical assessment data into regional magnetic compilations based on the levelled data.

Strengths

• Data was processed and levelled by a professional contractor, Aurora Geosciences Ltd.
• Four standardized derivative products (PDF grids) are provided for analysis.
• Data is integrated with existing 1:250,000 scale regional compilations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the underlying assessment reports are from before March 2015.
• The dataset's row count and exact file sizes are unknown, which may limit suitability assessment.
