1,391,556 gravity stations from the Australian National Gravity Database and a 2013 Riverina survey were used to generate this image. The Commonwealth, State and Territory Governments, mining industry, universities, and research organizations contributed data collected from the 1940s onward. Terrain corrections using offshore bathymetry and onshore topography were applied to produce the complete Bouguer anomalies displayed.
Use Cases
- Analyze subsurface geological structures based on complete Bouguer gravity anomalies.
- Identify potential mineral exploration targets based on gravity anomaly patterns.
- Study regional crustal density variations based on terrain-corrected gravity data.
- Integrate gravity data with other geophysical datasets for geological modeling.
- Visualize continental-scale gravity trends for educational or research purposes.
Strengths
- Derived from approximately 1.8 million gravity observations, specifically using 1,391,556 processed stations.
- Integrates data from multiple sources including government, industry, and academia collected over decades.
- Includes terrain corrections calculated using both offshore bathymetry and onshore topography data.
- Image-enhanced and displayed with sun shading for improved visual interpretation.
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 or temporal bias inherent to the collection sources.
