Recent geological mapping, stratigraphic drilling, and geophysical reassessment provide information on the structure of the Lander Trough in the Wiso Basin. The trough is a downwarp approximately 300 km long and 100 km wide, containing three rock sequences: a thin Late Palaeozoic sandstone, a wedge of Cambrian or Ordovician sediments up to 800 m thick, and Proterozoic basement. The data is provided by the Australian Ocean Data Network.
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.
- Correlate geological events based on references to the Alice Springs Orogeny.
- Map subsurface stratigraphy based on described thicknesses of sedimentary wedges.
Strengths
- Describes specific geological dimensions: a trough 300 km long and 100 km wide.
- Provides quantified rock sequence thicknesses ranging from 100-250 m to 800 m.
- Integrates multiple data sources: recent mapping, drilling, and geophysical reassessment.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data formats are PDF and HTML, which may require extraction for quantitative analysis.
