Julia Creek Sheet: Geological Map Explanatory Notes for Western Queensland

A 1961 geological mapping program by the Bureau of Mineral Resources' Great Artesian Basin Party produced this dataset. It covers the Julia Creek area, forming the western and northern margins of the Eromanga Sub-Basin in Western Queensland. The data describes Cretaceous rocks overlying a crystalline basement, with small outcrops of Precambrian granite and metamorphics in the southwest, and areas masked by Cainozoic and recent deposits.

Use Cases

• Analyze regional geological structure based on the described Cretaceous rock formations and basement.
• Study sediment cover and masking based on the described veneers of Cainozoic sand, gravel, and recent alluvium.
• Map Precambrian basement outcrops based on the described granite and metamorphic occurrences in the southwest.

Strengths

• Produced by a government geological survey (Bureau of Mineral Resources/Geoscience Australia).
• Provides specific geological context for the Julia Creek area and Eromanga Sub-Basin margins.
• Describes multiple geological eras (Precambrian, Cretaceous, Cainozoic, recent).

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 the specific mapped region.
