Holocene Terrigenous Sedimentation in the Central Great Barrier Reef Lagoon

The central Great Barrier Reef Province is characterized by a prograding terrigenous shoreline and an inner shelf dominated by fluvially derived mud. This dataset, from Geoscience Australia Data, models sedimentation patterns from the Burdekin River region, detailing coastal progradation rates and sedimentary assemblages. It was last updated on 2026-04-20.

Use Cases

• Modeling sediment dispersal from a major river point source based on the description of the Burdekin River.
• Analyzing coastal progradation rates and patterns based on described rates from 2.5 m yr-1 to 0.1 m yr-1.
• Identifying and classifying sedimentary assemblages (e.g., beach-ridge plain, chenier plain) in a prograding coastal wedge.
• Studying the seismic stratigraphic elements (coastal onlap, toplap) of preserved geological records as described.

Strengths

• Provides specific coastal progradation rates, from 2.5 m yr-1 to 0.1 m yr-1.
• Describes four distinct sedimentary assemblages (beach-ridge plain, chenier plain, mangrove-mud-flat plain, barrier bar-lagoon complex).
• Focuses on a well-defined geographic region: the central Great Barrier Reef lagoon and Burdekin River.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF and HTML formats, which may require extraction for computational analysis.
