Geological Synthesis of Queensland's Carpentaria and Karumba Basins

Geoscience Australia Data provides a geological bulletin synthesizing field surveys and geophysical investigations of the Mesozoic Carpentaria and Cainozoic Karumba Basins in north Queensland. The synthesis incorporates data from field surveys initiated in 1969 by the Bureau of Mineral Resources and Geological Survey of Queensland, supplemented by aerial photography, Landsat imagery, and stratigraphic drilling.

Use Cases

• Analyze geological structures and basin boundaries defined by Gulf of Carpentaria watersheds.
• Correlate stratigraphic sequences using data from shallow stratigraphic drilling and augering programs.
• Review geophysical survey data, including wire-line logs from water bores, for subsurface interpretation.
• Map regional geology using aerial photographs from the RC9 Series (1:80,000) and K17 series (1:48,000).

Strengths

• Synthesis incorporates decades of field surveys beginning in 1969.
• Mapping utilizes multiple data sources including aerial photography at 1:80,000 and 1:48,000 scales and Landsat imagery.
• Includes data from supplementary stratigraphic drilling and wire-line logging of bores.

Limitations

• Primary data is presented in synthesized report format (HTML, PDF), not as a structured, queryable dataset.
• Sample data and specific row/column counts for underlying measurements are unavailable.
• Temporal coverage of the source surveys is broad, potentially leading to inconsistent data resolution over time.
