Fitzroy River Basin Sediment Source Analysis Using Geochemical and Bayesian Modelling

Geochemical and Bayesian modelling data identify sediment sources in the Fitzroy River coastal zone. The study found basaltic material is now the dominant catchment source, with an estimated enrichment of ca. 3 relative to catchment abundances. Data from Geoscience Australia was last updated on 2026-04-20.

Use Cases

• Model changes in catchment sediment sources over time based on the Bayesian statistical model described.
• Analyze the impact of rainfall events and land-use changes on coastal sediment composition.
• Study the homogenization effect of hydrodynamic processes on coastal sediment geochemistry.
• Target land management practices by identifying areas supplying the majority of sediment to the coastal zone.

Strengths

• Analysis integrates geochemical data with a Bayesian statistical modelling approach.
• Study quantifies a specific enrichment factor (ca. 3) for basaltic material.
• Temporal analysis covers changes throughout the Holocene period.

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 bias inherent to the single river basin study.
