Geology of the Birdsville 4-Mile Sheet Area, Queensland

Geological mapping and water bore log analysis for the Birdsville 4-mile sheet area in Queensland. The work established a sequence of at least 3,000 feet of Mesozoic sediments and up to 100 feet of Tertiary rocks. The data was published by Geoscience Australia Data and was last updated in April 2026.

Use Cases

• Modeling groundwater flow based on the described Mesozoic aquifer and impermeable cap rock.
• Assessing petroleum source rock potential based on the marine shales of the Wilgunya Formation.
• Identifying potential reservoir rocks based on the sandstones of the Lower Cretaceous Longsight Sandstone.
• Regional geological correlation using the described stratigraphic sequence and unconformities.

Strengths

• Describes a specific, quantified geological sequence of at least 3,000 feet of Mesozoic sediments.
• Identifies specific geological formations with potential economic significance, such as the Wilgunya Formation and Longsight Sandstone.
• Provides spatial context with references to specific locations like the Bedourie Bore and Delhi Frome Santos Betoota No. 1 Well.

Limitations

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