Development, Composition and Age of Indurated Sand Layers in the Late Quaternary Coastal D

Analytical data from indurated sand layers in late Quaternary coastal deposits at Beachmere and Bells Creek in southeast Queensland. Samples were analyzed for cement composition, texture, and trace metal concentrations, with ages determined by OSL and TL methods. The dataset is provided by the Australian Ocean Data Network via data.gov.au.

Use Cases

• Modeling soil development and podzolisation processes based on cement composition and texture data.
• Analyzing groundwater flow and perched water table formation based on descriptions of hydraulic conductivity and cement precipitation.
• Studying trace metal geochemistry in coastal sediments by comparing cement concentrations to regional soils and modern estuarine sediments.
• Reconstructing geochronology of coastal deposits using OSL and TL age data spanning approximately 100,000 years.

Strengths

• Includes geochronological data with specific OSL and TL age ranges, such as 76,700 ±6,500 years and 98,000 ±9,900 years.
• Provides specific sample locations at Beachmere and Bells Creek in southeast Queensland.
• Describes detailed cement composition, including dominant constituents like kaolinite and amorphous organic-rich complexes.

Limitations

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