Terrigenous Sedimentation Model for the Central Great Barrier Reef Lagoon

The central Great Barrier Reef Province is characterised by a mainland prograding terrigenous clastic shoreline and an inner shelf dominated by fluvially derived mud. This dataset, sourced from Geoscience Australia Data, models sedimentation patterns from the Burdekin River region, describing coastal progradation rates decreasing from 2.5 m yr-1 to 0.1 m yr-1. It was last updated on 2026-05-14.

Use Cases

• Model sediment dispersal patterns based on the Burdekin River point source.
• Analyze coastal progradation rates based on described Holocene sedimentation rates.
• Study sedimentary assemblages based on described beach-ridge plains, chenier plains, and mangrove-mud-flat plains.
• Investigate seismic stratigraphic elements based on described coastal onlap, toplap, and marine offlap patterns.

Strengths

• Provides specific sedimentation 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).
• Sourced from the authoritative organization Geoscience Australia Data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Burdekin Region study area.
