Geological History of the Cairns-Townsville Hinterland, North Queensland

A geological history derived from regional mapping of 35,000 square miles in the Cairns-Townsville hinterland of North Queensland, conducted from 1956 to 1959. The description details the structure of the Precambrian Georgetown Shield and the adjacent Palaeozoic Tasman Geosyncline, including sediment thicknesses and igneous intrusions. The data is provided by Geoscience Australia Data.

Use Cases

• Model regional geological evolution based on described shield and geosyncline structures.
• Analyze sediment deposition patterns based on described thicknesses of up to 40,000 feet.
• Study igneous rock distribution based on described outcrops of acid, basic, and ultrabasic intrusions.
• Research tectonic events like the formation of the Broken River Rift mentioned in the description.

Strengths

• Covers a mapped area of 35,000 square miles.
• Describes specific geological features including a 200-mile-long shield and sediment thicknesses up to -40,000 feet.
• Based on fieldwork conducted over a defined period from 1956 to 1959.

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 temporal bias inherent to the 1956-1959 survey period.
