Surface Sediment Samples from the Tasmanian Shelf and Bass Strait

365 surface and near-surface seabed samples form the basis for an assessment of regional lithofacies variations on the Tasmanian shelf and in eastern and western Bass Strait. The dataset, provided by Geoscience Australia Data, includes analyses of sediment composition, heavy minerals, and geochemistry. It was last updated on 2026-04-30.

Use Cases

• Mapping regional lithofacies variations based on the described sediment types (e.g., quartz-rich sands, bryozoan gravels).
• Analyzing sediment provenance and transport history based on heavy mineral suites and relationships with the adjacent hinterland.
• Investigating geochemical anomalies, such as trace cassiterite or phosphatisation, mentioned in the description.

Strengths

• Based on 365 surface and near-surface seabed samples.
• Includes specific geochemical measurements, such as a maximum of 10 ppm Sn and 3.6 percent P2O5.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Sample station density is described as low in parts of the shelf, which may limit spatial analysis.
• Row count is unknown, which may limit suitability assessment.
