The Lander Trough in the southern Wiso Basin of Northern Territory contains geological mapping, stratigraphic drilling, and geophysical reassessment data. Beneath superficial material, three rock sequences are distinguished: Late Palaeozoic sandstone, Cambrian or Ordovician sediments and volcanics, and Proterozoic basement. The trough is a crustal downwarp approximately 300 km long and 100 km wide, bounded by a fault system linked to the Alice Springs Orogeny.
Use Cases
- Model basin structure based on described rock sequences and fault systems
- Assess petroleum potential based on the presence of thick Cambrian and Ordovician sediments
- Compare geological evolution with similar basins like the Amadeus Basin and Georgina Basin
Strengths
- Description includes specific geological sequences and their thicknesses (100-250 m, up to 800 m)
- Provides dimensions for the trough structure (300 km long, 100 km wide)
- Links the region's geology to known tectonic events (Alice Springs Orogeny) and analogous 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
