Geological History of the Cairns-Townsville Hinterland, North Queensland

A geological history derived from regional mapping of 35,000 square miles in North Queensland from 1956 to 1959. The description details the structure of the Georgetown Shield and Tasman Geosyncline, including sediment thicknesses and igneous intrusions. The dataset is provided by the Australian Ocean Data Network.

Use Cases

• Study regional metamorphism and uplift events based on descriptions of granulite, amphibolite, and migmatite formation.
• Analyze sediment deposition patterns based on thicknesses of pelagic, terrigenous, and organic sediments.
• Model tectonic history based on descriptions of shield fracturing, rift formation, and geosyncline deformation.

Strengths

• Based on regional mapping covering 35,000 square miles.
• Provides specific quantitative details, such as sediment thicknesses of 40,000 feet and 30,000 feet.
• Describes a long temporal history spanning from Precambrian to Permian periods.

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 and temporal bias inherent to the specific mapping project.
