Magnetic Lineaments for Structural Trends, 50m Gridded TMI Data

Lineaments interpreted from 50-meter gridded Total Magnetic Intensity (TMI) data. The dataset was compiled by GHD for the 'Potential Influences of Geological Structures on Groundwater Flow Systems' report for the Secure Allocation Future Entitlements (SAFE) Project. It focuses on NNE-SSW, ENE-WSW, and WNW-ESE structural trends not closely addressed by prior work from the former Department of Primary Industries.

Use Cases

• Mapping subsurface geological structures based on interpreted magnetic lineaments.
• Analyzing potential groundwater flow pathways based on identified structural trends.
• Validating or supplementing existing geological interpretations with specific NNE-SSW, ENE-WSW, and WNW-ESE trend data.

Strengths

• Derived from 50-meter gridded Total Magnetic Intensity (TMI) data, suggesting a specific spatial resolution.
• Interpreted with a focus on three specific structural trend orientations (NNE-SSW, ENE-WSW, WNW-ESE).
• Created for a formal report (the SAFE Project) by a named consultancy (GHD).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial extent are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
