Brighton Downs Sheet: Geological Reconnaissance Survey of Queensland, 1961

A reconnaissance survey of the Brighton Downs 4-mile Sheet area in Queensland was conducted by geologists R. R. Vine and W. Jauncey of the Bureau of Mineral Resources between June and August, 1961. The report describes Cretaceous rocks cropping out over nearly the whole area, with Lower Cretaceous marine sediments in the northwest and freshwater deposits of Lower to Upper Cretaceous age. Tertiary sedimentation areas in the north and southwest contain sandstone, clay, and limestone, with widespread lateritisation.

Use Cases

• Geological mapping based on the described rock formations and stratigraphy.
• Studying Cretaceous sedimentation patterns based on the described marine and freshwater deposits.
• Analyzing lateritisation processes based on the mention of its widespread occurrence.
• Researching Tertiary geological history based on the described sandstone, clay, and limestone deposits.

Strengths

• Survey conducted by named geologists R. R. Vine and W. Jauncey from the Bureau of Mineral Resources.
• Specific temporal coverage of the fieldwork from June to August 1961.
• Clear spatial focus on the Brighton Downs 4-mile Sheet area in Queensland.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
