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

The Lord Howe Rise, a submerged continental fragment off eastern Australia, is the focus of this dataset. It contains geophysical data from marine surveys, satellite observations, dredge samples, and shallow drilling to study its Cretaceous rifting from Gondwana. The data was presented at the 2016 American Geophysical Union Fall Meeting and is associated with Geoscience Australia.

Use Cases

• Modeling the drivers of continental rifting based on the extensional history described.
• Analyzing the tectonic affinity of igneous rocks within rift basins to distinguish between self-organizing and mantle-driven rifting scenarios.
• Studying the architecture of un-accreted continental ribbons using marine and satellite geophysical data.
• Planning future deep stratigraphic drilling (IODP) targets based on existing seismic survey data.

Strengths

• Data includes a recent deep crustal seismic survey across the Lord Howe Rise.
• Analysis is informed by a proposed IODP deep stratigraphic well through a rift basin.

Limitations

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