Geological mapping and 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 a maximum 100 feet of Tertiary rocks. The dataset was published by the Australian Ocean Data Network.
Use Cases
- Analyze aquifer structure based on the Mesozoic rock sequence and impermeable cap described.
- Evaluate petroleum source rock potential based on the marine shales of the Wilgunya Formation.
- Map geological unconformities based on the described Tertiary over Mesozoic sequence.
- Assess reservoir rock distribution based on the sandstones of the Lower Cretaceous Longsight Sandstone.
Strengths
- Describes a specific geological sequence of at least 3,000 feet of Mesozoic sediments.
- Identifies specific formations (Wilgunya Formation, Longsight Sandstone) and their roles.
- Provides concrete spatial references (e.g., Bedourie Bore 120 miles north, Delhi Frome Santos Betoota No. 1 Well 100 miles east).
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 bias inherent to data_gov_au.
