Amadeus Basin Hydrogeological Inventory With Geological Unit Details

An inventory of descriptive attributes for the Amadeus Basin sedimentary basin in central Australia, grouped into themes including Location, Geology, Hydrogeology, and Groundwater management. The basin contains sedimentary rock sequences with thicknesses ranging from 350 m to 14,000 m across multiple geological formations. It is an active hydrocarbon province with identified petroleum source rock units.

Use Cases

• Analyze geological unit thicknesses (e.g., Gillen Formation's 850 m, Winnall Group's 2,134 m) to model basin stratigraphy.
• Identify hydrocarbon source rock potential using data on units like the Horn Valley Siltstone and Pertatataka Formation.
• Assess groundwater management and use patterns by integrating hydrogeology and surface water theme data.
• Map spatial relationships between physical geography, land use, and groundwater features for environmental studies.
• Correlate sediment types (clastic, carbonate, evaporitic) from geology themes with depositional environment descriptions.

Strengths

• Contains detailed thickness measurements for geological units, such as the 6,000 m to 14,000 m total basin thickness.
• Groups descriptive data into 11 structured analytical themes including Hydrogeology, Geology, and Groundwater management.
• Documents specific formations like the Stairway Sandstone (544 m thick) and their composition, supporting detailed geological analysis.

Limitations

• Data is provided in PDF format, which is not readily machine-readable for direct analysis without extraction.
• Sample data and specific column definitions are unavailable, limiting understanding of the data structure.
• The spatial extent is defined only as the Amadeus Basin in central Australia without precise coordinate boundaries.
