Geology and Structure of the Lander Trough, Northern Territory

Geoscience Australia Data provides geological mapping, drilling, and geophysical reassessment data for the Lander Trough. The trough is a 300 km long by 100 km wide crustal downwarp containing up to 800 meters of Cambrian and Ordovician sediments. This data upgrades the area's petroleum potential by correlating it with gas-bearing, structurally similar basins to the south and southeast.

Use Cases

• Model subsurface geology based on described stratigraphic sequences and thicknesses.
• Assess petroleum potential based on the correlation with gas-bearing sequences in adjacent basins.
• Map regional tectonic structures based on the described overthrust fault system and basin geometry.
• Conduct stratigraphic analysis based on the described Proterozoic, Palaeozoic, and Cainozoic rock sequences.

Strengths

• Describes a specific geological structure approximately 300 km long and 100 km wide.
• Identifies sediment sequence thicknesses, such as a wedge up to 800 meters thick.
• Correlates the area's petroleum potential with proven gas-bearing basins.

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/temporal bias inherent to data_gov_au.
