Lord Howe Rise Continental Ribbon: Seismic and Geophysical Data on Cretaceous Rifting

A 2016 abstract presents geophysical data on the Lord Howe Rise, a submerged continental fragment formed during the Cretaceous period. The dataset, hosted by the Australian Ocean Data Network, includes marine and satellite geophysical data, dredge samples, and shallow drilling results. It aims to resolve the tectonic drivers behind the rifting of eastern Gondwana.

Use Cases

• Modeling the extensional history of a continental ribbon based on seismic survey data.
• Investigating the drivers of plate tectonics based on the composition and tectonic affinity of igneous rocks.
• Comparing self-organizing versus mantle-driven rifting scenarios using stratigraphic and geophysical evidence.

Strengths

• Data is derived from a recent deep crustal seismic survey across the Lord Howe Rise.
• Includes multiple data sources: marine geophysical data, satellite data, dredge samples, and shallow drilling.

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.
• Knowledge of rift basins is based on widely-distributed and sparse data, with drilling limited to less than 600 meters below seafloor.
