The Lander Trough, southern Wiso Basin, Northern Territory

Recent geological mapping, shallow drilling, and geophysical reassessment provide new information on the Lander Trough's rock sequences and structure. The report distinguishes three rock sequences beneath superficial material, including a thick (up to 800 m) Cambrian-Ordovician wedge that upgrades the area's petroleum potential. This data was published by Geoscience Australia and last updated on 2026 03 25.

Use Cases

• Assessing petroleum potential based on described thick Cambrian and Ordovician sediment sequences
• Modeling basin structure based on the described 300 km long, 100 km wide downwarp and overthrust fault system
• Correlating regional geology based on comparisons to the Amadeus and Georgina Basins mentioned in the description
• Stratigraphic analysis based on the three distinguished rock sequences (Proterozoic, Early Palaeozoic, ?Late Palaeozoic)

Strengths

• Description includes specific geological measurements, such as sequence thicknesses of 100-250 m and up to 800 m
• Provides spatial context with a defined trough length (300 km) and width (100 km)
• Integrates multiple data sources: recent mapping, stratigraphic drilling, and reassessed geophysical data

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is presented in PDF/HTML report formats, which may require extraction for computational analysis
