A geological history derived from mapping 35,000 square miles of the Cairns-Townsville Hinterland from 1956 to 1959. The description details a Precambrian shield flanked by a Palaeozoic geosyncline containing up to 40,000 feet of sediments and intruded by extensive igneous rocks. This dataset is hosted by the Australian Ocean Data Network.
Use Cases
- Modeling regional tectonic evolution based on described shield and geosyncline structures.
- Analyzing sediment deposition patterns based on thicknesses of 30,000 and 40,000 feet.
- Studying igneous intrusion events based on mapped areas of acid and basic/ultrabasic rocks.
- Investigating metamorphic processes based on described granulite, amphibolite, and migmatite formations.
Strengths
- Based on regional geological mapping covering 35,000 square miles.
- Provides detailed quantitative measurements, such as sediment thicknesses of 40,000 feet and igneous rock outcrop areas of 20,000 and 5,000 square miles.
- Describes a complex geological 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/temporal bias inherent to data_gov_au.
