Aurora Geosciences Ltd reprocessed publicly available digital magnetic geophysical data from assessment reports submitted to the Government of Yukon prior to March 2015. Individual data were levelled and integrated with 1:250,000 scale compilations. The output includes four gridded PDFs: residual total magnetic field, reduced to pole, vertical derivative, and tilt derivative.
Use Cases
- Mineral exploration targeting based on processed magnetic field anomalies.
- Geological mapping and structural analysis based on derivative magnetic grids.
- Integrating historical assessment data into regional compilations based on the 1:250,000 scale.
Strengths
- Data underwent a levelling and integration process with 1:250,000 compilations.
- Includes four standardized derivative products (residual, reduced to pole, vertical derivative, tilt derivative).
- Original data sources are documented in YGS Open File 2017-27.
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 only reports submitted prior to March 2015.
