Sedimentology and Holocene History of Broad Sound, Queensland Estuary

Late Holocene sediment data from Broad Sound, Queensland, a tropical estuary with a 10-meter tidal range. The dataset, provided by Geoscience Australia Data, includes textural, petrological, and mineralogical studies of sediments from environments like mangrove swamps and sand ridges. Radiocarbon dating indicates sea level stabilized approximately 6000 years ago, followed by shoreline progradation.

Use Cases

• Modeling regressive sedimentary sequences based on the described 'fining upward' stratigraphy.
• Analyzing sediment transport patterns based on described landward and seaward movements of terrigenous and calcareous material.
• Classifying estuarine environments using grainsize parameters as described in the textural studies.
• Studying Holocene sea-level change using the evidence that sea level stabilized about 6000 years ago.

Strengths

• Includes radiocarbon dating establishing a late Holocene age for most sediments.
• Describes a clear environmental model based on sediment grainsize parameters.
• Covers multiple distinct environments within the estuary system, such as mangrove swamps and sand ridges.
• Provides a specific tidal range measurement of 10 meters for the study area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified despite a last updated date of 2026-04-30.
