Laura Basin Hydrogeological Inventory with Stratigraphic Descriptions

A hydrogeological inventory for the Laura Basin in Australia, containing descriptive attribute information grouped into themes like location, geology, hydrogeology, and groundwater management. The dataset describes sedimentary rocks deposited between 168 and 102 million years ago, with strata reaching a maximum thickness of about 1,000 meters. It is provided by the Australian Ocean Data Network via data.gov.au.

Use Cases

• Model groundwater flow and storage based on described hydrogeological features.
• Analyze sedimentary basin evolution based on stratigraphic unit descriptions (Rolling Downs Group, Gilbert River Formation, Dalrymple Sandstone).
• Assess groundwater management potential based on themes covering groundwater use and environment.
• Study geological history and paleoenvironments based on depositional environment descriptions (shallow marine, lagoonal, fluvial).
• Integrate spatial groundwater features with thematic attribute data for regional geological mapping.

Strengths

• Descriptive information is organized into 11 specific thematic groups, including Geology, Hydrogeology, and Groundwater Management.
• Provides detailed stratigraphic data, including three main units with named formations and depositional environments.
• Includes specific temporal context for rock deposition, spanning from 168 to 102 million years ago.
• Specifies a maximum strata thickness of about 1,000 meters in the north-central part of the basin.

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 solely on the Laura Basin region.
