Delamerian Orogen Geological History Plots for Mainland Australia

Two holistic time-space plots and a map detail the geological history of the Delamerian Orogen across central and eastern Australia. The dataset synthesizes recent multi-disciplinary data from Geoscience Australia's Exploring for the Future program and the MinEx CRC National Drilling Initiative. It covers a spatial extent of approximately 1500 km by 300 km and a temporal range from about 830 to 495 million years ago.

Use Cases

• Compare magmatism and sedimentation ages across the orogen based on the detailed time-space plot traverses.
• Analyze the impact of younger geodynamic events on the orogen based on the overview geological history.
• Correlate lithological and geochemical data with geological events based on the integrated datasets referenced.
• Map the spatial distribution of deformation and mineralisation based on the provided location map and plots.

Strengths

• Spatial coverage spans five Australian states over an area approximately 1500 km long by 300 km wide.
• Temporal coverage spans from the Archaean to the present, with detailed focus from the Ediacaran to the end of the Devonian.
• Integrates recent multi-disciplinary data from major geological survey programs like Exploring for the Future and MinEx CRC.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The orogen is described as poorly exposed and mostly covered by younger basins, which may limit direct observational data.
