The Lord Howe Rise continental ribbon dataset presents geophysical and geological data related to the Cretaceous fragmentation of eastern Gondwana. It includes marine and satellite geophysical data, dredge samples, and shallow drilling results from the Australian Ocean Data Network. The dataset was presented at the 2016 American Geophysical Union Fall Meeting and was last updated in April 2026.
Use Cases
- Modeling the extensional history of a continental ribbon based on stratigraphy preserved in rift basins.
- Distinguishing between self-organizing and mantle-driven plate motion scenarios based on igneous rock composition.
- Analyzing the drivers of continental rifting using data from a recent deep crustal seismic survey.
- Investigating the influence of silicic Large Igneous Provinces on rifting events.
Strengths
- Data includes results from a recent deep crustal seismic survey across the Lord Howe Rise.
- Dataset leverages multiple data sources including marine geophysical data, satellite data, dredge samples, and shallow drilling.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic/temporal bias inherent to data_gov_au.
