5028 Block 3 (Northwest) Grid: Potassium Ground Concentration for Narryer Region

415,090 line-kilometres of radiometric data were acquired in 2024 to produce this grid of potassium concentration. The processed data shows potassium element concentration of the Narryer region in units of percent, with a cell size of approximately 20 meters. Geoscience Australia geophysicists checked the processed data for quality to ensure it is fit-for-purpose.

Use Cases

• Map subsurface geological structures based on potassium concentration variations.
• Identify potential mineral deposits based on radiometric signatures.
• Conduct environmental baseline studies using natural gamma-ray spectrometry data.
• Validate geological models with high-resolution ground concentration measurements.

Strengths

• Data covers 415,090 line-kilometres, indicating a substantial survey area.
• Processed via NASVD and standard reductions to ensure response is due only to ground rocks.
• Quality-checked by GA geophysicists to be fit-for-purpose.
• High-resolution grid with a cell size of approximately 20 meters.

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 geographic bias inherent to the specific survey block in Western Australia.
