Lord Howe Rise Continental Ribbon: Geophysical and Stratigraphic Data

Geoscience Australia Data presents geophysical and stratigraphic data related to the Lord Howe Rise, a submerged continental fragment. The dataset includes marine and satellite geophysical data, dredge samples, and shallow drilling records from Cretaceous rift basins. It was last updated on 2026-03-25 and is associated with research presented at the 2016 American Geophysical Union Fall Meeting.

Use Cases

• Modeling the extensional history of a continental ribbon based on stratigraphic data.
• Distinguishing between self-organized and mantle-driven rifting scenarios based on igneous rock composition.
• Analyzing crustal architecture and its influence on global climate and oceanic circulation patterns.
• Integrating marine geophysical data with seismic survey results for tectonic studies.

Strengths

• Associated with a recent deep crustal seismic survey across the Lord Howe Rise.
• Includes data from a proposed IODP deep stratigraphic well through a rift basin.
• Last updated on 2026-03-25, indicating recent metadata maintenance.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is based on widely-distributed geophysical data and sparse shallow drilling (<600 m below-seafloor).
