Australian Continental Margin Sediment Geochemistry and Magnetic Susceptibility

11 gravity cores from the west, south, and east Australian continental margin were analyzed for magnetic susceptibility, calcium carbonate, and elemental composition. Geoscience Australia Data produced this dataset, which includes isotopic data for chronological control on some cores, identifying periods like the Last Glacial Maximum. The data shows correlations between magnetic susceptibility and terrigenous material content across the sampled regions.

Use Cases

• Reconstructing past climate conditions based on down-core magnetic susceptibility and calcium carbonate profiles.
• Analyzing sediment accumulation rates and isotopic stages using the provided chronological control data.
• Investigating the relationship between terrigenous material and magnetic susceptibility in marine sediments.
• Comparing geochemical patterns across different regions of the Australian continental margin.

Strengths

• Data is derived from 11 sampled gravity cores across three distinct geographic regions.
• Includes isotopic data (8180 and 14C) for chronological control on specific cores.
• Analysis covers multiple geochemical variables: magnetic susceptibility, percent calcium carbonate, Fe2O3, Al2O3, and SiO2.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Chronological data is not available for all sampled areas, as noted in the description.
• Row count is unknown, which may limit suitability assessment.
