Aurora Geosciences Ltd reviewed 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, reduced to pole, vertical derivative, and tilt derivative.
Use Cases
- Mineral exploration targeting based on processed magnetic field derivatives.
- Geological mapping and structural interpretation based on integrated 1:250,000 scale compilations.
- Geophysical data quality assessment and standardization based on the review of legacy assessment reports.
Strengths
- Data has been levelled and integrated with regional 1:250,000 scale compilations, suggesting improved consistency.
- Four derivative products (residual, reduced to pole, vertical derivative, tilt derivative) provide multiple analytical perspectives.
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 only data submitted before March 2015 was considered.
