Geological Survey of Carpentaria and Karumba Basins in Northern Australia

Field surveys for this geological bulletin began in 1969 by the Bureau of Mineral Resources and the Geological Survey of Queensland. The work synthesizes information from geological mapping, geophysical surveys, and stratigraphic drilling in the region. It includes maps and data covering the Mesozoic Carpentaria Basin and the overlying Cainozoic Karumba Basin.

Use Cases

• Analyze basin boundaries and watersheds from geological maps for structural modeling.
• Correlate stratigraphic sequences using data from shallow drilling and wire-line bore logs.
• Supplement aerial photograph interpretation with Landsat imagery for regional geological mapping.
• Review geophysical survey data to understand subsurface characteristics of the basins.

Strengths

• Synthesizes geological investigations spanning from 1969 onward.
• Incorporates multiple data sources: field surveys, aerial photographs, Landsat imagery, and geophysical surveys.
• Includes stratigraphic data from drilling and augering programs.

Limitations

• Primary data formats are PDF and HTML reports, requiring manual extraction for computational analysis.
• Specific sample sizes, row counts, and quantitative data metrics are not provided.
• Temporal coverage for the underlying data collection is broad but not precisely quantified.
