Lander Trough Geological Structure and Stratigraphy, Northern Territory

The Lander Trough in the southern Wiso Basin, Northern Territory, is described through recent geological mapping, stratigraphic drilling, and geophysical reassessment. The data distinguishes three rock sequences beneath superficial material, including Late Palaeozoic, Cambrian-Ordovician, and Proterozoic units, with thicknesses up to 800 meters. It was published by Geoscience Australia Data, with a metadata update timestamp of 2026-04-20.

Use Cases

• Model subsurface basin structure based on described stratigraphic sequences and fault systems.
• Assess petroleum potential based on comparisons to similar basins where gas has been found.
• Conduct geological mapping and interpretation based on integrated geophysical and drilling data.

Strengths

• Integrates multiple data sources including geological mapping, stratigraphic drilling, and geophysical data.
• Provides specific dimensional estimates for the trough (approximately 300 km long and 100 km wide) and rock sequence thicknesses (100-800 m).

Limitations

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