Geomorphological Evolution and Carbonate Production at Lord Howe Island

Geomorphological Evolution of Lord Howe Island and Carbonate Production at the Latitudinal Limit to Reef Growth is a dataset from the Australian Ocean Data Network. It describes the island's volcanic structure, Quaternary carbonate sediments, and its position as the southernmost coral reef in the Pacific. The dataset was last updated in April 2026.

Use Cases

• Classify erosional landforms like plunging cliffs or shore platforms based on underlying lithology such as Mount Lidgbird Basalt or calcarenite.
• Model the temporal sequence of sediment deposition using dating methods like uranium-series and amino acid racemisation tied to marine oxygen isotope stages.
• Analyze the composition shift in shelf sediments from a coral-dominated fringing reef to a more temperate biota veneer.
• Map the spatial relationship between the volcanic island, its broad shelves, and the fringing reef development on the western side.

Strengths

• Focuses on a unique location at the latitudinal limit to coral reef growth in the Pacific.
• Integrates multiple dating methods (uranium-series, amino acid racemisation, thermoluminescence) for temporal analysis.
• Describes a clear geological history spanning approximately 6 million years from basalt eruption to present reef.

Limitations

• Specific data volume, row count, and column details are unavailable.
• The primary data format is HTML, which may not be structured for direct computational analysis.
• Sample data is unavailable, preventing assessment of data granularity and structure.
