Ngalia Basin Stratigraphy and Structure in Northern Territory, Australia

The Ngalia Basin contains up to about 5 km of sedimentary rock, with maximum known thicknesses including 3200 m of Adelaidean and 3100 m of Devono-Carboniferous sediments. This dataset from the Australian Ocean Data Network describes the basin's stratigraphy, structure, and resource potential. It was last updated on 2026-06-04.

Use Cases

• Modeling basin evolution based on described periods of sedimentation and diastrophism.
• Assessing petroleum potential based on the analysis of unconformities and source rocks.
• Evaluating uranium mineralization potential confined to the Devono-Carboniferous continental sandstone.
• Studying groundwater resources from described Devono-Carboniferous and Cainozoic aquifers.

Strengths

• Description includes specific sediment thickness measurements, such as 3200 m for Adelaidean and 3100 m for Devono-Carboniferous.
• Provides a detailed structural analysis, describing the basin as a faulted easterly trending asymmetrical syncline.
• Covers multiple geological time periods from Adelaidean to late Palaeozoic.

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 formats, which may require extraction for computational analysis.
