Australian East Coast Sea Level Indicators from Sand Deposits and Dune Morphology

An investigation of beach-sand heavy-mineral deposits conducted by the Bureau of Mineral Resources between 1948 and 1950. The work involved detailed boring and sampling of beaches, coastal dunes, and plains along the coast from the Clarence River, New South Wales, to North Stradbroke Island, Queensland. Results related to changing sea levels are summarized in the publication.

Use Cases

• Reconstruct historical sea-level changes based on the levels of water-laid sand-deposits.
• Analyze coastal evolution and dune morphology based on detailed boring and sampling data.
• Study heavy-mineral deposits for geological mapping and resource assessment along the Australian east coast.

Strengths

• Fieldwork conducted over a multi-year period from 1948 to 1950.
• Detailed sampling methodology included borehole levels determined in relation to high water mark.
• Covers a specific geographic transect from northern New South Wales to southern Queensland.

Limitations

• Data is presented in PDF/HTML reports; underlying structured data files are not specified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
