Geological and Borehole Data Compilation for Southwestern Victoria and South Australia

South-western Victoria and the contiguous part of South Australia, specifically the Portland-Nelson-Mt Gambier area, are the focus of this geological report. The dataset is a compilation of geological, bore-hole, and well data, along with a geological sketch map, created by the Australian Ocean Data Network. It was last updated on 2026-04-28.

Use Cases

• Analyze subsurface stratigraphy based on compiled bore-hole and well records.
• Identify potential structural features at depth based on the recommendation for a geophysical survey.
• Study the geological history and topography of the area based on the report's overview.
• Map the distribution of marine Tertiary rocks and underlying basement rocks based on the compiled geological information.

Strengths

• Compiles data from scattered exposures and principal bores in a region with poor surface exposure.
• Includes a geological sketch map to visualize the compiled information.
• Report provides an overview of general geology, history, stratigraphy, and topography.

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 in PDF and HTML formats, which may require extraction for computational analysis.
