Indurated Sand Layers in Northern Moreton Bay, Queensland

Samples from sand mine pits at Beachmere and an estuarine channel at Bells Creek in southeast Queensland were analysed for indurated sand layers. The dataset includes optical and thermoluminescence (OSL/TL) ages indicating induration processes occurring over periods up to approximately 100,000 years. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Modeling long-term soil development processes based on cement composition and age data.
• Analyzing the relationship between sediment texture and induration degree based on described gravely vs. medium-coarse sand comparisons.
• Investigating groundwater flow and cement precipitation in coastal deposits as described for the Beachmere exposures.
• Assessing trace metal concentrations in historical coastal cements compared to modern sediments.

Strengths

• Includes specific OSL and TL age ranges, such as 76,700 ±6,500 years and 98,000 ±9,900 years.
• Describes distinct cement forms and constituents like kaolinite and amorphous organic-rich complexes.
• Provides comparative analysis of induration rates over different time periods (e.g., last 16,000 ±2,600 years).

Limitations

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