Radiometric Lineaments Interpreted from 50m Gridded Data for Geological Analysis

Lineaments interpreted from 50m gridded radiometrics data, including Total Count, Potassium, Thorium, and Uranium channels. The dataset was compiled by GHD for the DEPI SAFE Project report 'Potential Influences of Geological Structures on Groundwater Flow Systems'. It was last updated on 2026-04-09.

Use Cases

• Identify ENE-WSW and NNW-SSE trending geological lineaments based on radiometric data.
• Map strandlines and basin faults in coastal regions like the Otway Basin based on described parallel lineaments.
• Correlate soil radiometric chemistry changes with topographic lineaments to infer paleo-fault movement.
• Create pseudo-geomorphology maps by combining radiometric and topography datasets as described.

Strengths

• Derived from 50m gridded radiometrics data, providing a regional-scale resolution.
• Includes multiple data layers: plain rasters, topography-draped channels, and RGB false colour images.
• Interpretation links radiometric soil chemistry changes (within 0.5m depth) to topographic features.

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.
