Indurated Sand Layers in Northern Moreton Bay Coastal Deposits, Queensland

Australian Ocean Data Network hosts a dataset on indurated sand layers in late Quaternary coastal deposits of northern Moreton Bay, Queensland. Samples were analyzed from exposures at Beachmere and Bells Creek, examining cement composition, trace metal concentrations, and deposition ages. The dataset likely contains analytical results from samples used to study the timing and processes of sand induration over periods up to approximately 100,000 years.

Use Cases

• Modeling soil development timelines based on optically stimulated luminescence (OSL) and thermoluminescence (TL) age data mentioned in the description
• Analyzing the relationship between sediment texture and induration degree based on described comparisons of gravelly sands versus medium to coarse sands
• Studying groundwater flow and cement precipitation processes in poorly sorted sediments as described for the Beachmere exposures
• Assessing trace metal concentrations in historical cements compared to modern soils and sediments as referenced in the description

Strengths

• Includes specific age estimates for deposits, such as 76,700 ±6,500 years and 98,000 ±9,900 years
• Describes analysis of distinct cement forms with dominant constituents like kaolinite and amorphous organic-rich complexes
• Provides a temporal context for induration processes, indicating it occurs over long periods up to approximately 100,000 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 data_gov_au, focusing solely on southeast Queensland sites
