Geological And Borehole Data For Southwestern Victoria And South Australia

A compilation of geological and subsurface data from south-western Victoria and the contiguous part of South Australia, focusing on the Portland-Nelson-Mount Gambier area. The Australian Ocean Data Network compiled this report, which includes tabulated borehole and well records, a geological sketch map, and an overview of the region's geology. The dataset was last updated in April 2026.

Use Cases

• Analyze borehole records to map subsurface stratigraphy and identify formations from Tertiary to Recent periods.
• Correlate well data with geological sketch maps to study the structure of the Murray River Artesian Basin extension.
• Use compiled geological history and topography data for regional landform and geological hazard assessment.

Strengths

• Compilation includes data from the principal bores in the area examined in detail.
• Report integrates geological, bore-hole, well data, and a geological sketch map.
• Data covers a large territory in south-western Victoria and south-eastern South Australia.

Limitations

• Direct geological information is severely limited by poor surface exposure of underlying rocks.
• Specific row counts, column details, and sample sizes for the tabulated data are unknown.
• Primary data format is a PDF/HTML report, which may require extraction for quantitative analysis.
