An investigation of beach-sand heavy-mineral deposits conducted by the Bureau of Mineral Resources between 1948 and 1950. The work covers the coastline from the Clarence River in New South Wales to North Stradbroke Island in Queensland, involving detailed boring and sampling of beaches, dunes, and coastal plains. Results related to changing sea levels are summarized from the Bureau's publications.
Use Cases
- Reconstruct historical sea-level positions based on described sand deposit levels and bore-collar measurements.
- Analyze coastal dune morphology and sediment composition for paleoenvironmental studies.
- Correlate heavy-mineral deposits with past coastal processes and geological events mentioned in the description.
Strengths
- Fieldwork conducted over a multi-year period from 1948 to 1950.
- Spatial coverage includes a defined coastal region from northern New South Wales to southern Queensland.
- Data includes detailed bore-collar levels determined in relation to high water mark.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Primary data formats are PDF and HTML, which may require extraction for computational analysis.
