Geochemical Analysis of Estuarine Sediments from Broad Sound, Queensland

A geochemical dataset from estuarine sediment samples in Broad Sound, Queensland, analyzed using Q-mode and R-mode factor analysis, discriminant analysis, and regression. The data was published by Geoscience Australia Data and was last updated in March 2026. It identifies processes controlling concentrations of P2O5, Cu, Pb, and Zn in supratidal and intertidal zones.

Use Cases

• Classifying sediment depositional environments based on geochemical composition.
• Modeling the relationship between pH/Eh and trace metal concentrations like Cu, Pb, and Zn.
• Identifying geochemical processes controlling phosphate (P2O5) absorption on clay particles.
• Analyzing the stability of pH and Eh readings over time in sediment samples.

Strengths

• Analysis is supported by multiple statistical techniques including Q-mode factor analysis and stepwise discriminant analysis.
• The description details specific geochemical processes for trace elements (Cu, Pb, Zn) and phosphate.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
