Burdekin River Region Geological Mapping Bulletin

A geological bulletin summarizes regional mapping results for a 67,000 km² area near Townsville, Queensland. The work was conducted by the Bureau of Mineral Resources and the Geological Survey of Queensland from 1961 to 1967. It details the geological evolution from the Precambrian/Cambrian through to the Cainozoic, including sedimentary basin development and orogenic events.

Use Cases

• Analyzing the tectonic evolution of the Lolworth-Ravenswood Block using descriptions of its formation as a structural high via granitic intrusion.
• Correlating sedimentary sequences across the Burdekin, Drummond, and Bowen Basins using described stratigraphic cycles and marine/continental condition alternations.
• Investigating the timing and impact of orogenic events like the Tabberabberan and Kanimblan Orogenies on basin destruction and subsequent igneous activity.
• Studying the economic geology potential by examining the formation context of units like the Collinsville Coal Measures within the Permian Bowen Basin sequence.

Strengths

• Covers a large mapped area of approximately 67,000 square kilometers.
• Provides a synthesized geological history spanning from the Precambrian/Cambrian to the Cainozoic era.

Limitations

• Primary data is presented as a summarized bulletin in PDF/HTML, not as structured, machine-readable data tables.
• The underlying fieldwork and mapping occurred from 1961-1967, representing historical interpretations that may be superseded.
