5028 Block 1 (Southwest) Grid: Potassium Ground Concentration at 20m Resolution

415,090 line-kilometres of radiometric survey data acquired in 2024 by the WA Government were processed to produce this potassium concentration grid. Geoscience Australia geophysicists performed quality checks to ensure the data are fit-for-purpose for revealing sub-surface geological structure. The final grid has a cell size of approximately 20 meters and shows potassium element concentration in the Narryer area in units of percent.

Use Cases

• Map subsurface potassium distribution for mineral exploration based on gamma-ray spectrometric measurements.
• Interpret geological structure and rock types based on processed radiometric element concentrations.
• Validate or integrate regional geochemical models using a quality-checked, government-acquired grid.

Strengths

• Data volume is precisely quantified at 415,090 line-kilometres.
• Acquisition parameters are specified: 100m line spacing and 50m terrain clearance.
• Processing methods (NASVD and standard reductions) are applied to isolate the rock response.
• Quality assurance was performed by GA geophysicists to ensure fitness-for-purpose.

Limitations

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