Geology of the Carpentaria and Karumba Basins in Northern Australia

A geological bulletin synthesizing information on the Mesozoic Carpentaria Basin and overlying Cainozoic Karumba Basin in northern Queensland and the eastern Northern Territory. The work is based on field surveys beginning in 1969 by the Bureau of Mineral Resources and the Geological Survey of Queensland, supplemented by geophysical surveys, stratigraphic drilling, and Landsat imagery. The dataset was last updated on 2026-04-30.

Use Cases

• Map regional geological structures based on the synthesis of field surveys and geophysical data.
• Analyze basin stratigraphy and evolution based on information from shallow drilling and borehole logs.
• Study landform interpretation based on the use of aerial photographs and Landsat imagery mentioned in the description.

Strengths

• Synthesizes geological information from field surveys initiated in 1969, providing a long-term perspective.
• Incorporates multiple data sources including aerial photography, Landsat imagery, and geophysical surveys.
• Includes data from shallow stratigraphic drilling and wire-line logging of water bores.

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/temporal bias inherent to the specific survey areas.
