5028 Block 1 (Southwest): Thorium Ground Concentration Grid for Narryer Region

2024 radiometric survey data from the Narryer region, processed to show thorium concentration in parts per million. The grid is based on 415,090 line-kilometres of data collected at 100m line spacing and 50m terrain clearance by the WA Government. Geoscience Australia performed quality checks to ensure the data is fit-for-purpose for geological interpretation.

Use Cases

• Map subsurface geological structures based on thorium concentration patterns.
• Identify potential mineral resources based on radiometric signatures.
• Conduct environmental baseline studies based on natural radioactivity levels.
• Integrate with other geophysical datasets for regional geological modeling.

Strengths

• Data is derived from a large-scale 2024 survey covering 415,090 line-kilometres.
• Processing includes standard reductions and NASVD to isolate the rock response.
• Quality checks were performed by Geoscience Australia geophysicists.
• 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.
