Arafura Basin Hydrogeological Inventory with Geological and Groundwater Attributes

Geoscience Australia Data provides a hydrogeological inventory for the Arafura Basin, a large sedimentary basin spanning over 250 million years from the late Neoproterozoic to early Permian. The dataset groups descriptive attributes into themes including location, geology, hydrogeology, groundwater management, and land use. It was last updated on 2026-04-20.

Use Cases

• Model regional groundwater flow based on described fractured sandstone aquifers like the Marchinbar Sandstone.
• Analyze the relationship between sedimentary rock sequences and aquifer properties based on the described Wessel, Goulburn, and Arafura Groups.
• Assess groundwater resource potential for remote community supply based on historical investigations mentioned for Maningrida, Galiwinku, and Millingimbi.
• Study paleoenvironmental conditions based on described shallow marine and fluvial depositional settings.

Strengths

• Covers a large geological time span of over 250 million years.
• Groups information into 11 thematic categories including hydrogeology, groundwater management, and environment.
• Includes specific geological unit names such as the Wessel Group and Marchinbar Sandstone.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided as PDF, which may hinder direct computational analysis.
