Northern Moreton Bay in Queensland contains samples of indurated sand from Quaternary coastal deposits. The dataset includes analysis of cement composition and optical and thermoluminescence dating, indicating induration processes occurring over periods up to approximately 100,000 years. It was published by Geoscience Australia Data and last updated in May 2026.
Use Cases
- Modeling groundwater flow based on the described lower hydraulic conductivity of indurated layers.
- Analyzing trace metal concentrations in coastal sediments compared to modern estuarine samples.
- Studying the relationship between sediment texture and the degree of induration over time.
- Reconstructing past regional soil development phases from cemented sand horizons.
Strengths
- Includes specific OSL and TL age ranges, such as 76,700 ±6,500 years and 98,000 ±9,900 years.
- Describes detailed cement composition analysis, identifying constituents like kaolinite and amorphous organic-rich complexes.
- Provides 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.
- Freshness should be verified as the last update date is 2026-05-14.
