Geology of the Birdsville 4-Mile Sheet Area, Queensland

Mapping and bore log analysis established a sequence of at least 3,000 feet of Mesozoic sediments in the western Great Artesian Basin. The report, likely from Geoscience Australia, identifies the Mesozoic rocks as the main aquifer and the Wilgunya Formation as a potential petroleum source rock. No oil or gas has been reported from water bores in the area, and no important economic mineral deposits are present.

Use Cases

• Model groundwater aquifer characteristics based on described Mesozoic sediment sequences.
• Assess petroleum source rock potential based on the identified Wilgunya Formation.
• Study regional geology and stratigraphy for the western Great Artesian Basin.
• Correlate borehole data from the Birdsville area with other geological surveys.

Strengths

• Report includes specific geological measurements, such as a 3,000-foot Mesozoic sequence and a 100-foot maximum Tertiary thickness.
• Identifies specific geological formations (e.g., Wilgunya Formation, Longsight Sandstone) and their properties.

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, focusing on a specific Queensland sheet area.
