Indurated Sand Layers in Late Quaternary Coastal Deposits of Northern Moreton Bay

OSL and TL ages indicate induration processes occurring over periods of 100,000 ± 70,000 years, with only incipient development in the last 16,000 ± 2,600 years. Samples from sand mine pits and estuarine channels in southeast Queensland were analyzed for cement composition and trace metal concentrations. The dataset is hosted by the Australian Ocean Data Network and was last updated in 2026.

Use Cases

• Modeling long-term soil development and podzolisation processes based on described cementation ages and mineral constituents.
• Assessing groundwater flow and perched water table formation based on the described hydraulic conductivity of indurated layers.
• Analyzing regional trace metal geochemistry by comparing cement concentrations to reported soil and sediment levels.
• Investigating the influence of sediment texture on induration degree, as suggested by the comparison of gravely sands to medium-coarse sands.

Strengths

• Provides specific geochronological data, including OSL ages of 76,700 ±6,500 years and 98,000 ±9,900 years.
• Describes distinct cement forms and constituents, such as kaolinite and amorphous organic-rich complexes.
• Includes comparative analysis of trace metal concentrations against regional soils and modern 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.
