Description
The southern Taroom Trough and overlying Surat Basin in Australia are documented through isopach, structure contour, and palaeo-geological maps. The dataset, published by the Australian Ocean Data Network, describes a 50,000 km² trough with up to 10,000 m of sedimentary fill and a 300,000 km² basin with up to 2500 m of Jurassic and Cretaceous sediments.
Use Cases
Modeling basin subsidence and compaction history based on described sedimentary thickness and structural features.
Assessing petroleum prospectivity based on described source rocks and reservoir sandstones like the Hutton Sandstone.
Reconstructing palaeo-geography and tectonic evolution based on isopach and structure contour maps.
Analyzing sediment distribution patterns from described Permian to Cretaceous depositional sequences.
Strengths
Covers a large, defined geographic area of 50,000 km² for the Taroom Trough and 300,000 km² for the Surat Basin.
Provides specific geological metrics, including maximum sedimentary thicknesses of 10,000 m and 2500 m.
Includes detailed stratigraphic and tectonic history with named formations and structural features.
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.
Provenance
Source
Australian Ocean Data Network
Collection Method
Likely compiled from geological surveys and research.
Time Range
Covers geological periods from the Lower Permian to the Lower Cretaceous.
