Distribution of Triassic Reefs in the Northern Exmouth Plateau and Offshore Canning Basin

A 34-day research cruise in early 1990 aimed to acquire 2500 km of multichannel seismic profiles, about 15 dredges, and up to 5 cores. The project by the Australian Ocean Data Network's Marine Division assesses the petroleum potential of Triassic and Jurassic carbonate reefs on Australia's Northwest Shelf. It maps known reef complexes on the Wombat Plateau and extends the analysis into the Canning Basin.

Use Cases

• Mapping Triassic/Jurassic carbonate facies changes based on seismic profiling and dredging techniques mentioned in the description
• Assessing petroleum prospectivity of reef traps based on the description of reef complexes forming potential reservoirs
• Defining the geological history of the northern Exmouth Plateau based on the project's stated aim to better define the area's history

Strengths

• Project involved acquisition of 2500 km of multichannel seismic profiles
• Aims to collect about 15 dredge samples and up to 5 cores
• Focuses on a specific geological target: Triassic and Jurassic carbonate reefs

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
