Lord Howe Rise Continental Ribbon: Geophysical Data on Gondwana Fragmentation

The Lord Howe Rise continental ribbon dataset contains 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 data was presented at the 2016 American Geophysical Union Fall Meeting.

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 and tectonic affinity.
• Analyzing the tectonic setting and evolution of submerged continental crust using marine geophysical survey data.

Strengths

• Includes data from a recent deep crustal seismic survey across the Lord Howe Rise.
• Contains information from a proposed IODP deep stratigraphic well through a rift basin.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
