Lord Howe Island in the southwestern Pacific Ocean contains stratigraphic data on skeletal carbonate eolianite and beach calcarenite. The data likely includes lithostratigraphic divisions, cement types, karst features, and a chronology constructed from U/Th, TL, AMS 14C, and amino acid racemization dating. The dataset is hosted by the Australian Ocean Data Network.
Use Cases
- Modeling coastal carbonate depositional phases based on the record of up to 7 discrete phases mentioned in the description
- Analyzing paleosol development and climate cycles based on the clay-rich and weakly developed fossil soil horizons described
- Studying karstification processes based on the described outcrop features such as dolines, caves, and speleothems
- Correlating eolianite deposition with sea-level changes based on the described sediment source location seaward of and below the present shoreline
Strengths
- Chronology is constructed from multiple dating methods: U/Th ages of speleothems and corals, TL ages of dune and paleosols, AMS 14C and AAR dating
- Stratigraphy is detailed, dividing deposits into two formations (Searles Point and Neds Beach) based on lithostratigraphy and bounding horizons
- Depositional phases are identified, with data indicating emplacement during oxygen isotope stages 7, 5e, and 5a
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
