Indurated Sand Layers in Northern Moreton Bay, Queensland: Composition and Age

Northern Moreton Bay, Queensland, features samples from sand mine pits and estuarine channels analyzed for cement composition and age. The dataset likely contains geochemical and sedimentological measurements from indurated sand layers, including cement constituents and trace metal concentrations. It was published by Geoscience Australia Data and last updated on 2026-03-25.

Use Cases

• Modeling soil development phases based on indurated sand horizon characteristics mentioned in the description
• Analyzing groundwater flow and cement precipitation processes based on sediment texture and mineralogy
• Assessing trace metal concentrations in historical coastal cements compared to modern sediments
• Dating coastal depositional events using Optically Stimulated Luminescence (OSL) and Thermoluminescence (TL) age data

Strengths

• Includes specific OSL/TL age ranges for deposits, such as 76,700 ±6,500 years and 98,000 ±9,900 years
• Describes cement composition with specific constituents like kaolinite and amorphous organic-rich complexes
• Compares trace metal concentrations in cements to regional soils and modern estuarine sediments

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 specific study sites at Beachmere and Bells Creek
