Maryborough-Nambour Basin: Hydrogeology and Stratigraphy

Geoscience Australia's dataset details the hydrogeology of two adjoining sedimentary basins in Queensland, where the geological boundary has shifted due to reclassification of Cretaceous and Jurassic rock units. It provides descriptive attribute information grouped into themes including geology, hydrogeology, groundwater management, land use, and environment. The data supports the National Hydrogeological Inventory, characterizing basins with up to 100 meters of Cenozoic sediments and specific formations like the 450-meter-thick Landsborough Sandstone.

Use Cases

• Groundwater resource assessment based on hydrogeological unit descriptions and aquifer characteristics.
• Basin evolution studies using detailed stratigraphic data on Cretaceous and Triassic-Jurassic rock units.
• Environmental impact analysis for land use planning, referencing themes on land use, industry, and surface water.
• Scientific research into sedimentary basin architecture, leveraging information on formation thicknesses and compositions.

Strengths

• Produced by Geoscience Australia, a national geological survey organization, indicating authoritative sourcing.
• Structured around specific, detailed thematic groups (e.g., Hydrogeology, Groundwater management) for organized analysis.
• Part of the National Hydrogeological Inventory, suggesting integration into a larger, standardized national framework.

Limitations

• Critical metadata is missing or conflicting: row count, size, license, and author are listed as 'unknown' or 'None' across all sources.
• The dataset's core attribute columns are not specified ('unknown'), limiting understanding of its granular structure.
• Update timestamps conflict, with one source showing '2026-03-07' and others '2026-05-14', creating uncertainty about versioning.
