Description
Isopach, structure contour, and palaeo-geological maps illustrate the geological development of a 50,000 km² trough and a 300,000 km² overlying basin. The dataset, from Geoscience Australia, includes details on sedimentary fill thickness, tectonic history, and petroleum potential. It was last updated on 2026-05-14.
Use Cases
Model basin subsidence and compaction history based on described isopach and structure contour maps.
Assess petroleum prospectivity in Lower Jurassic sandstones based on described migration and trapping discussions.
Reconstruct palaeo-environments and sediment deposition based on described sequences of marine, coal, and stream sediments.
Analyze tectonic fault timing and basin structural features like the Mimosa and Dirranbandi synclines.
Strengths
Covers a large, defined geographic area of 350,000 km² combined for the two basins.
Describes specific geological features and sequences, including thickness ranges from less than 400 m to 10,000 m.
Includes discussion of petroleum sources and potential prospective areas like the Bollon area.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is presented in HTML format, which may require extraction for computational analysis.
Provenance
Source
