5028 Block 4 (Northeast) Grid: Potassium Ground Concentration for Narryer, Australia

415,090 line-kilometres of radiometric survey data were acquired in 2024 by the WA Government to produce this potassium concentration grid. Geoscience Australia processed the data via standard methods and quality checks to ensure a response from only subsurface rocks. The resulting grid has a cell size of approximately 20 meters, showing potassium element concentration in the Narryer region as a percentage.

Use Cases

• Model subsurface geological structure based on potassium concentration variations.
• Map regional mineral composition for resource exploration based on gamma-ray spectrometry.
• Validate geological models by comparing processed radiometric data with known rock formations.

Strengths

• Data collection scale is precisely quantified at 415,090 line-kilometres.
• Acquisition parameters are specified: 100m line spacing and 50m terrain clearance.
• Data underwent standard processing and quality checks by GA geophysicists to be fit-for-purpose.

Limitations

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