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

Samples from exposures at Beachmere and Bells Creek in southeast Queensland were analysed for indurated sand layers in late Quaternary coastal deposits. The dataset includes OSL and TL ages indicating induration processes over periods up to 100,000 ± 70,000 years. It was published by Geoscience Australia Data and last updated on 2026-04-20.

Use Cases

• Modeling past soil development phases based on indurated sand horizon descriptions.
• Analyzing groundwater flow and perched water table formation based on hydraulic conductivity properties.
• Studying trace metal concentrations in historical cements compared to modern sediments.
• Correlating sediment texture with the degree of induration over geological timescales.

Strengths

• Includes specific geochronological data with OSL and TL ages, such as 76,700 ±6,500 years.
• Describes detailed cement composition, including kaolinite and amorphous organic-rich complexes.
• Provides comparative analysis of induration over distinct time periods, like the 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.
• Data may reflect geographic bias inherent to the two specific sample sites in southeast Queensland.
