Lineaments from 250m Gridded Gravity Data for Structural Analysis

Lineaments interpreted from 250m gridded Bouguer gravity data, reduced using a bedrock density of 2.67 T/m3. 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 interpreting 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 structural trends based on interpreted gravity lineaments.
• Analyzing potential influences on groundwater flow systems based on interpreted geological structures.
• Correlating gravity-derived lineaments with other geological datasets for regional studies.

Strengths

• Derived from 250m gridded gravity data, providing a specific spatial resolution.
• Focuses on specific structural trends (NNE-SSW, ENE-WSW, WNW-ESE) not covered in prior work.
• Uses an industry-standard Bouguer reduction density of 2.67 T/m3.

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.
