5028 Block 4 (Northeast): Reduced Magnetic Survey Data for Narryer, 2024

415,090 line-kilometres of Total Magnetic Intensity data were acquired over the Narryer region in 2024. The dataset is processed with corrections for diurnal variation, geomagnetic reference fields, and levelling to highlight subsurface geology. It was published by Geoscience Australia Data and last updated in May 2026.

Use Cases

• Geological mapping based on processed Total Magnetic Intensity variations.
• Mineral exploration targeting based on magnetic anomalies in the Earth's crust.
• Environmental subsurface studies based on the corrected magnetic field data.

Strengths

• Contains 415,090 line-kilometres of data, indicating a large survey area.
• Data has been processed with five specific reductions, including diurnal correction and micro-levelling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
